# FMScriptBridge — script text: the writing rules

**Grammar version:** 1.113 · **spec build:** f518ab53

Which version you need: a plug-in accepts text written to its own grammar
version and to every earlier one. A form introduced in a later version is
refused at its line, never pasted wrong. To match the installed plug-in
exactly, use its `FMSB_CopyAISpec` function: the copy it makes carries that
plug-in's own version in these first lines.

This document defines the text form FileMaker script steps are written in.
It is a rulebook: what you may write, and what refuses. You read and write
ONLY this text — never FileMaker XML.

## 1. Absolute rules

1. **Return raw script text only.** No prose before or after the script.
   Do not wrap the script in a markdown code fence and do not add any
   fence of your own — the only backtick fences that may appear are the
   calc and comment fences defined in §2. A fence line (three or more
   backticks alone) anywhere else refuses the whole push.
2. **Never edit inside a `>>> preserved-fmxml` block.** Any change
   inside this block corrupts the step — copy the whole block
   byte-for-byte, fence lines included. Delete the whole step only if
   the user asked for that step to be removed.
3. **Never invent a name or spelling.** Step names, option labels and
   enum values must be spelled exactly as in this document or in text
   you were given. The same for field, table, layout and script names:
   write only names the user gave you; any other name pastes broken.
4. **When a step or option is not covered** by this document or the text
   you were given, do not guess it. Write this comment step instead, and
   say so in your reply channel if you have one:
   `# TODO: <step name> - add by hand in FileMaker`
5. **Fence every multi-line calculation.** A `[ … ]` bracket body may
   never simply continue onto the next line: either keep the
   calculation on ONE line, or write it inside a fence (the fenced
   forms in §2 — opener on its own line after the `label:` header, the
   closing fence line carrying the step's ` ]`).
6. **Never alter a fence or its body.** The closing fence repeats the
   opening fence's backtick run exactly; never shorten, lengthen or
   move a fence you were given, and never reflow, re-indent or re-wrap
   the lines between the fences — fence-body lines are data, byte for
   byte. Open a NEW fence with exactly three backticks (more only when
   the body itself contains a three-backtick run). In a ` ```cr `
   fence, keep every line exactly as given; never open a `cr` fence
   yourself. To write intentional leading
   whitespace on a fence-body line of your own, put it beyond the
   opener line's leading whitespace. Indentation on ordinary STEP
   lines, by contrast, is free — write any; 4 spaces per If/Loop level
   is the convention.
7. **Keep inline `[ … ]` items in the order shown** for that step —
   the shown order is always safe; no reordering. Text after a
   calculation or path slot is part of that value — never place an
   item after such a slot except in the exact shapes this document
   shows with one (Set Field By Name's second slot, Show Custom
   Dialog's message, Perform Script on Server's wait item). Option
   lines directly inside a BLOCK step's bracket may be written in any
   order; lines inside a `{ … }` sub-block and find-request criteria
   keep their order — order is data there.
8. **Never replace `#!#REDACTED#!#`.** It marks a redacted secret in
   text you were given — leave it exactly as it is.
9. **Write real FileMaker calculation syntax** — real function names,
   real signatures. A calculation that does not compile is pasted
   commented out as `/*…*/`.
10. **Return the COMPLETE script.** Every step you were given must appear
   in your answer, in order. Never abbreviate, elide or summarise a run
   of steps. `# ... rest unchanged ...` is a legal comment step, so it
   is accepted silently and the steps you left out are simply GONE from
   the user's script — this is the one mistake here that destroys work
   rather than refusing.
11. **A step line ends at its closing `]`.** There are no end-of-line
   comments. Put the note on its own line ABOVE the step as `# note`.
   A note left after the `]` usually refuses the line — but do not rely
   on that: an inline value slot runs to the line's TERMINAL `]`, so a
   note that itself contains a `]` supplies a new terminal one and is
   ABSORBED INTO THE VALUE instead. `Set Variable [ $x ; Value: 1 ]
   // note]` is accepted, with the value silently becoming `1 ] // note`.
   Beware also that `//` is not a comment marker here even though
   FileMaker calculations use it as one — a line STARTING with `// `
   means that step is DISABLED (§2 `disabled`). Inside a calculation,
   by contrast, `//` is ordinary calculation text and is kept.
12. **The item separator is ` ; ` — one space on each side, exactly.**
   Not `;`, not ` ;`, not `; `, not `  ;  `. This is what tells an item
   separator apart from a semicolon that is calculation DATA: plug-in
   calls such as `MBS("Dyna.Save"; $pdf; "out.pdf")` separate their own
   arguments with `; `, and those must stay inside the value. Just
   inside the brackets, `[ $x … ]` and `[$x … ]` both read — but that
   is the only latitude: extra padding (`[  $x …  ]`) refuses, exactly
   as a mis-spaced separator does. Copy the spacing you were given.

If an edit cannot be expressed within these rules, say so and leave the
step unchanged.

### Step names

A step name must match this list exactly; any other name refuses.
Names are separated by ` · `; a line break also separates — no name
spans a line break. The 216 names:

## 3. Reserved tokens

Each literal below is grammar, never field or calc data:

| Token | Meaning |
|---|---|
| ```` ``` ```` | calc / preserve fence delimiter (the ```cr opener marks a copy-only fence — rule 6) |
| `>>> preserved-fmxml` | opens a preserve-verbatim raw-FM-XML block |
| `<<<` | closes a preserve-verbatim block |
| `[ ## not-yet-pretty: preserved verbatim ## ]` | optional header line above a preserve block |
| `→` | find-criteria delimiter in a predicate block (`field → operator-value`) |
| `<table-missing>` | unresolved table reference |
| `<field-missing>` | unresolved field reference |
| `<layout-missing>` | unresolved layout reference |
| `<script-missing>` | unresolved script reference |
| `<calc-missing>` | missing by-calculation script name (Perform Script) |
| `<file-missing>` | missing external file reference (Perform Script) |
| `<flow-missing>` | missing Claris Connect flow |
| `<name-missing>` | missing variable name (Set Variable) |
| `<no-target>` | Set Field / Set Selection with no target field |
| `<unmapped>` | Import Records target slot with no bound field |
| `<current>` | Truncate Table: the current table (no explicit reference) |
| `<none>` | Perform Script on Server with Callback: no callback script |
| `<unknown>` | FileMaker's own literal <unknown> reference text |
| `<Current Table>` | Truncate Table: FileMaker's literal current-table name |
| `[File Default]` | Install Menu Set: use the file-default menu set |
| `(collect across found set)` | Send Mail To/Cc/Bcc: collect addresses across found set |
| `[no condition]` | If / Else If with no Calculation (empty condition) |
| `#!#REDACTED#!#` | redacted-secret placeholder — leave exactly as given (rule 8) |
| `#! fmsb-missing-ref:` | advisory line — leave or delete whole; never edit or write one |
| `# ` | comment step - the ONLY comment form, and it owns its whole line |
| `// ` | DISABLE prefix: turns the following step off. NOT a comment |

Writing rules for four of these: an EMPTY If/Else If condition is written
`If [ no condition ]` — no inner brackets (`If [ [no condition] ]` makes
the literal text the formula). `[File Default]` is written inside quotes
AND ALONE in an Install Menu Set line — exactly
`Install Menu Set [ "[File Default]" ]`; the `Use as file default:`
option may only accompany a NAMED menu set
(`Install Menu Set [ "My Menus" ; Use as file default: On ]`), never
`"[File Default]"`. `→` delimits sort items inside a `SortList { … }`
sub-block exactly as it delimits find criteria. `<current>` is written
with its label in a Truncate Table line
(`Truncate Table [ With dialog: Off ; Table: <current> ]`).

Every other token in the table: copy it unchanged where text you were
given carries it; never introduce one yourself. A `#! fmsb-missing-ref:`
advisory line in given text may be left in place or deleted whole —
never edited, never written by you. A comment step whose text begins
`⚠ ATTENTION [` follows the same rule, and one more: it is always ONE
line, however long. Leave the whole line or delete the whole line — never
re-word it, and never wrap or split it. It is addressed to the person
reading the script, not to you; do not act on what it says.

## 4. Writing steps

**Shapes are fixed per step.** Some steps are inline (`Name [ … ]`), some
are a block (`Name [` alone on its line, indented `Label: value ;` option
lines, `]` alone). Copy the shape from text you were given or from an
example here, and write block steps as blocks (a block step written on
one line may still be accepted, but the block is always safe); an inline
step written as a block refuses. When editing text you were given, keep
every step in the shape it came in and change only the values you mean
to change. For a sub-block's inner lines (a `{ … }` under a label, a
find-request block) copy the form from that step in text you were given
or an example here; with neither, rule 4.

**Labels and enum values are exact spellings.** Copy them character for
character from this document or from text you were given. Boolean labels
differ per step (`With dialog:` on most, `Select entire contents:` on the
Insert family, others again) — never translate or normalize one. A typo'd
label, an unknown enum value or a duplicated option line refuses.

**Omitting options.** On the steps listed here — Send Mail, New Window,
Sort Records, Show Custom Dialog, Create Data File, Open Data File,
Write to Data File, Read from Data File, Close Data File, Select
Window, Move/Resize Window, Close Window, Open URL, Go to Field, Insert
Text, Perform Script on Server, Go to Related Record, Insert Calculated
Result, Insert Current Date, Insert Current Time, Insert Current User
Name, Insert File, Insert from Device (Camera source), and every step
in the short-form list below — you may write only the options you mean;
each omitted option takes FileMaker's own untouched-step default. What
you DO write always wins. For any OTHER step, write the full shape from
text you were given or an example — never rely on omission there.

**`Step [ ]` — empty brackets mean "FileMaker's defaults".** FileMaker's
own Script Workspace displays an untouched option-bearing step that way
(`Set Field [ ]`, `Go to Field [ ]`, `Perform Quick Find [ ]`), and that
form is accepted for every step: it builds the step exactly as FileMaker
creates it, with every option at its factory value. The block-structure
steps are the exception and still refuse — `If [ ]`, `Else [ ]`,
`End If [ ]`, `Loop [ ]` and friends are not option-bearing steps.

**The bare name and `[ ]` are NOT always the same step.** For most steps
they are, but two differ, and the difference is real state:

- `Enter Find Mode` is the step with no pause at all; `Enter Find Mode [ ]`
  is FileMaker's default, which PAUSES. (FileMaker reads an absent pause
  setting as Off — it does not fill in its default — so the bare name
  really does mean "do not pause".)
- `Close Window` closes the current window with no target set;
  `Close Window [ ]` is FileMaker's default, which limits to windows of
  the current file.

Write the bare name when you mean the minimal step, `[ ]` when you mean
"however FileMaker would have made it". If you are unsure, write the
options out.

**Short forms that parse** (write them exactly like this):

- `Perform Find` · `Show All Records` · `Omit Record` · `Exit Script` ·
  `Constrain Found Set` · `Extend Found Set` · `Enter Find Mode` ·
  `Close Window`: the bare name alone. Other steps bare-name only if
  you have seen them written bare in given text; otherwise rule 4.
- `Commit Records/Requests [ With dialog: Off ]`
- `Enter Find Mode [ Pause: Off ]`
- `Go to Layout [ "Name" ]`
- `Go to Record/Request/Page [ First ]` (also `Last`, `Previous`, and
  `Next ; Exit after last: On`)
- `Set Variable [ $x ; Value: … ]`
- `Set Field [ Table::Field ; <calc> ]` — the calculation is POSITIONAL:
  no `Value:` label here (that label belongs to Set Variable; written
  here it becomes part of the formula).
- `Set Field By Name [ <name-calc> ; <value-calc> ]` — the two calc
  slots split at the top-level ` ; `; separators inside parentheses or
  quotes are data.
- `Perform Script [ "Name" ; Parameter: … ]`
- `Exit Script [ Result: … ]` — and with no result, bare `Exit Script`
  or `Exit Script [ Text Result: ]`.
- `Show Custom Dialog [ <title-calc> ; <message-calc> ]` — the two-item
  positional dialog (default buttons). For buttons use the labeled
  block form in the examples; for input fields copy the lines from text
  you were given, else rule 4.
- `Open URL [ "https://…" ]` — and the browser checkbox is FileMaker's
  own `In external browser` token: write it when the box is checked, omit
  it entirely when it is not
  (`Open URL [ With dialog: On ; In external browser ; "https://…" ]`).
- `Go to Field [ Table::Field ]`
- `Pause/Resume Script [ Duration (seconds): 2 ]`
- `Select Window [ Current window ]` / `Select Window [ by name: "Name" ]`
- `Perform Script on Server [ "Name" ; Parameter: … ;
  Wait for completion: Off ]` — the wait item may sit first or last;
  omitted means On.
- An EMPTY `Parameter:` means no parameter at all, on the whole Perform
  Script family — it is FileMaker's own display for an unset one. Write
  `Parameter: "…"` when you mean a parameter that is literally blank.
- `Perform Script on Server with Callback [ Server script: "Name" ]` —
  the one-line form; `Wait for callback:` and `Callback:` may be omitted
  and take FileMaker's fresh-step state (`Continue` / `<none>`).
- The whole If / Else If / Else / End If / Loop / End Loop family, with
  the condition inline: `If [ Get ( FoundCount ) > 0 ]`.

**FileMaker's own display spellings that are also accepted:**
`Exit Script [ Text Result: … ]` · New Window's `Name:` /
`Style:` / `Using layout:` labels · `Current Window` capital-W on the
window steps · `Duration (seconds):` on Pause/Resume Script · a
bare `Select` token ALONE in the brackets on the select-family steps
(= `Select entire contents: On`; in any longer item list write the full
label instead — except Insert Calculated Result, where the calc may
follow it: `[ Select ; <calc> ]`) · a `Specified: From list` item on the
Perform Script family · Send Mail's `Send via E-mail Client` line (do
not combine it with `Via SMTP: On` or `Via OAuth: On`) · a dialog-only
sort written inline (`Sort Records [ With dialog: On ]`) · the
positional display forms `Speak [ <calc> ]`,
`Perform Quick Find [ <calc> ]`, `Set Selection [ <field> ]`,
`Set Next Serial Value [ <field> ; <calc> ]`,
`Omit Multiple Records [ With dialog: On/Off ; <count> ]` and
`Go to Object [ Object Name: <calc> ]` · Install OnTimer Script's own
line, which puts the quoted script name FIRST with no label and
`Interval:` LAST (`Install OnTimer Script [ "Name" ; Parameter: <calc> ;
Interval: <calc> ]`) — omit `Parameter:` entirely when there is none, as
an empty `Parameter:` is refused on this step, and
`Install OnTimer Script [ Interval: <calc> ]` is accepted with no name ·
Select Window's `Name:` label
with an optional bare `Current file` token (write the token for On,
omit it for Off: `Select Window [ Name: <calc> ; Current file ]`) · a quoted NAME may use
the curly double quotation marks `“ ”` in place of the straight `"` —
`Perform Script [ “Load Saxon” ]`. Both ends must match: a name opened
with one and closed with the other is refused. It is the outer pair only
that may be curly; whatever sits between them is kept exactly as written,
so `Perform Script [ ““Saxon”” ]` names the script `“Saxon”`, and only
that pair of characters is accepted. The steps that take it are
`Perform Script`, `Perform Script on Server`,
`Perform Script on Server with Callback`, `Go to Layout`,
`Install Menu Set` and `Truncate Table`, in the one-line form, plus the
names after `from file:`, `Server script:`, `Callback:` and `Table:`,
the block form of the steps that HAVE one (`Perform Script`,
`Perform Script on Server`, `Perform Script on Server with Callback`),
and the `Script "Name"` / `Folder "Name"` wrapper headers.

Nowhere else. In every OTHER name slot a curly mark is literal text and
becomes part of the name: `Set Variable [ “$x” ; Value: 1 ]` names the
variable `“$x”`, not `$x`. A calculation is the same — `Parameter:` and
every other calculation slot take a straight `"` as FileMaker's own string
delimiter, and a curly mark inside one is data.

NOTE where escaping applies. In the `Script "Name"` / `Folder "Name"`
wrapper headers, and on a block-form name line, a straight quotation mark
inside the name is written `\"` and a literal backslash `\\`. In the
ONE-LINE bracket forms the straight border is taken LITERALLY: everything
between the outer pair is the name exactly as written, so write
`Perform Script [ "S"p" ]`, not `Perform Script [ "S\"p" ]`, and a
backslash there is part of the name. In a curly border the mark is always
written plainly.

**Every option label is FileMaker's own word, and the same underlying flag
can be named differently on different steps.** Three that a generator gets
wrong by analogy:

- `Open File [ Open hidden: On|Off ; file: "…" ; path: <path> ]` — the flag
  is shown in BOTH states. Write the `file:` label, the quoted name and the
  `path:` item whenever you have the path; a file reference binds by NAME, and
  the path is what lets FileMaker add a data source it does not already have.
  The name ALONE is also accepted, with or without the label and with or
  without the flag (`Open File [ Open hidden: On ; "Name" ]`,
  `Open File [ "Name" ]`), and binds to an existing data source of that name;
  an omitted `Open hidden:` is Off, FileMaker's own default. `Close File`
  carries no flag (`Close File [ file: "…" ; path: <path> ]`); `Re-Login` puts
  the reference after its own `With dialog: On|Off`; and Perform Script's
  `from file:` takes the same `path:` item.
- `Constrain Found Set [ Restore ; Find without indexes ]` — both are BARE
  tokens, written only when on, and `Restore` comes first.
- `Perform Find [ Restore ]` — the bare token, never `Restore: On`; on this
  step the saved find's `{ … }` request block must follow on the next
  lines.
  Write bare `Perform Find` when there is no saved find.

**The rest of the vocabulary follows the same rule.** Write
the word FileMaker's own line or dialog shows, never a tag name:

- Flags that FileMaker shows only when on are BARE tokens, written only
  when on and omitted when off: `Verify SSL Certificates`, `Do not
  automatically encode URL`, `Skip Indexes`, `Allow Folder Creation`,
  `Expire password`, `No style`, `Stream`, `Agentic mode`, `Table`,
  `Delete`, `Match case`, `Match whole words only`, `Skip auto-enter
  options`. Convert File's `Open File` is such a token too (write it to
  open the file after conversion). Flags FileMaker shows in both states
  keep `On|Off`: `Current file only:`, `Lock:`, and Set Error Logging's
  own `[ On ]` / `[ Off ]`.
- A `Parameters:` item on Insert Embedding, Perform Find by Natural
  Language, Perform SQL Query by Natural Language and Generate Response
  from Model IS the Parameters checkbox: write it (empty or with the calc)
  to tick the box, omit it to clear it. Likewise the Print PDF items
  `Password:`, `Save print options to:` and `Use print options from:`,
  written inside its `Print settings: { … }` block, are their own
  checkboxes — present means on.
- Popup choices are the popup's words: `Sort Records by Field [ Descending ]`
  (or `Ascending` / `Associated value list`), `Find Matching Records
  [ Constrain ]` (`Replace` / `Extend`), `Configure Regression Model
  [ Action: Save Model ; Algorithm: Random Forest ]`, `Configure Region
  Monitor Script [ Monitor: Geofence ]`, `Set Zoom Level [ Lock: Off ;
  Zoom In ]` (or a percentage such as `150%`), `Training Data: File` on
  Fine-Tune Model, and `Authenticate via: Google` on Add Account (the
  popup's entries; `Microsoft Entra ID (Group)` / `Custom OAuth (Group)`
  for the Group radio). Any other spelling is refused, not guessed.
- `Perform Find/Replace [ With dialog: On ; Find Next ]` is the whole
  line for a fresh step (`Replace` / `Replace All` / `Replace & Find` are
  the other Perform words). The dialog's other settings appear only when
  they differ from the fresh step: `Match case`, `Match whole words
  only`, `Search across: Current record/request`, `Search within:
  Current field`, `Direction: Backward` or `Direction: All`.
- Replace Field Contents with serial numbers: `Serial numbers` alone means
  the field's entry options; add `( Initial value: 1 ; Increment by: 1 )`
  for custom values and `Update serial number in Entry Options` inside
  the same parentheses to tick that box; the separate `Skip auto-enter
  options` token means auto-enter is NOT performed (FileMaker's own
  default for this dialog).

**New Window / Go to Related Record / Go to List of Records window options are
WORDS.** The
`Dim parent:`, `Toolbars:` and `Menu bar:` lines carry the window's real
state; write `Yes`/`No`. A `Styles:` line holding a raw number appears
only where a window carries a setting the words cannot express — copy it
through untouched if you see one, and never invent one.

**Other rules:**

- **Finish every block you open.** A step written in the block form must
  reach its closing `]` on its own line (or ``` ] when the body ends in a
  fenced calculation). A block left unclosed is refused outright rather
  than guessed at — if your answer is cut off mid-step, the whole push is
  rejected, not half-applied.
- To disable a step, prefix ONLY its first line with `// ` — a block
  step's inner lines and closer stay unprefixed.
- Quote literal text values with `"…"` (FileMaker calc syntax; backslash
  escapes for embedded quotes). Field references and variables are bare.
- `text:` on Insert Text is LITERAL text — no quotes, not a calculation.
  A multi-line literal is fenced exactly like a multi-line calculation
  (rule 5): `text:` alone, the fence, the lines, the closing fence.

## 5. Examples

Each block below is exact:

#### Inline step (bracket body, ` ; `-separated items)

```
Set Variable [ $total ; Value: $x + 1 ]
```

#### Inline calc is opaque to the terminal `]` (embedded ` ; ` is data)

```
Set Variable [ $v ; Value: List ( 1 ; 2 ; 3 ) ]
```

#### Fenced multi-line calc (``` opener; body verbatim, block-in-brackets)

````
If [
```
a
and b
``` ]
````

#### Fenced multi-line calc as ONE ITEM of an inline body (the common shape)

````
Set Field [ Invoice::Total ;
```
Let ( [
  base = 1 ;
  tax = base * 2
] ;
  base + tax
)
``` ]
````

#### Comment — single line (the multi-line form uses a plain fence after a lone `#`)

```
# set up the loop
```

#### Disabled step (`// ` prefix)

```
// Perform Script [ "Child" ; Parameter: "param" ]
```

#### Whole-script wrapper (`Script "name" { … }`)

```
Script "MyScript"
{
    # set up
    Set Variable [ $i ; Value: 1 ]
}
```

#### Preserve-verbatim block (copy byte-for-byte; never edit inside)

```
Some Future Step  [ ## not-yet-pretty: preserved verbatim ## ]
>>> preserved-fmxml
<Step enable="True" id="99999" name="Some Future Step"><MysteryChild weird="1">data</MysteryChild></Step>
<<<
```

### Minimal generation forms

Write these shapes exactly:

#### Send Mail — recipient/subject/message is enough (e-mail client mode; configure the account in FileMaker)

```
Send Mail [
  To: "ops@example.com" ;
  Subject: "Nightly import" ;
  Message: "See attached"
]
```

#### New Window — name and layout are enough (Document style, standard controls)

```
New Window [
  Layout: "Orders" ;
  Window Name: "Report"
]
```

#### Sort Records — the sort order is enough (no dialog, order restored)

```
Sort Records [
  SortList {
    Orders::Customer → Ascending
    Orders::Total → Descending
  }
]
```

#### Show Custom Dialog — block form, any Button 1..3 subset

```
Show Custom Dialog [
  Title: "Delete?" ;
  Message: "This cannot be undone" ;
  Button 1 (commit): "Delete" ;
  Button 2: "Cancel"
]
```

#### Data files — one omitted option each (Create folders / Write as / Read as take factory values); Open Data File is a block

```
Create Data File [ Target file: $path ]
Open Data File [
  Source file: $path ;
  Target: $fileID
]
Write to Data File [ File ID: $fileID ; Data source: $text ]
Read from Data File [ File ID: $fileID ; Target: $out ]
Close Data File [ File ID: $fileID ]
```

#### Control flow — conditions inline, bodies indented 4 per level

```
If [ Get ( FoundCount ) > 0 ]
    Loop [ Flush: Always ]
        Set Field [ Invoices::Status ; "Overdue" ]
        Go to Record/Request/Page [ Next ; Exit after last: On ]
    End Loop
End If
```

#### Find pattern — enter find mode, set criteria as data, perform

```
Enter Find Mode [ Pause: Off ]
Set Field [ Invoices::Status ; "Open" ]
Set Field [ Invoices::Due_Date ; "<" & Get ( CurrentDate ) ]
Perform Find
```

#### Subscripts and results

```
Perform Script [ "Refresh_Tokens" ; Parameter: "force" ]
If [ Get ( ScriptResult ) = -1 ]
    Exit Script [ Result: -1 ]
End If
```

#### Everyday one-liners — the URL / field target / duration slot is enough (omitted options take factory values)

```
Open URL [ "https://status.example.com" ]
Go to Field [ Invoices::Status ]
Pause/Resume Script [ Duration (seconds): 2 ]
```

#### Windows — select by name, resize with just the dimensions you mean (Current window is the factory target)

```
Select Window [ by name: "Reports" ]
Move/Resize Window [
  Height: 600 ;
  Width: 900
]
```

#### Perform Script on Server — FileMaker's own display order; omit the wait item for the factory On

```
Perform Script on Server [ "Nightly Rebuild" ; Parameter: "full" ; Wait for completion: Off ]
```

#### Insert Text — BLOCK form; `text:` is LITERAL text (no quotes, not a calculation), `Target:` is a field or variable

```
Insert Text [
  text: Reviewed - do not edit ;
  Target: Orders::Note
]
```

## 6. If the user relays a message

- **A refusal naming one line** (`push failed at line N: …`): fix that
  line and resubmit — everything before it was fine. (A Script body
  opens with `{` alone on the line after the header and closes with `}`
  alone; there is no `End Script`.)
- **A warning** (`line N was understood differently` / `line N is not in
  the converted result` / `near line N the result carries an extra
  line` / `push-verify: line N - …`): the text WAS converted, but line N
  may not mean what you intended — recheck it against §4 and correct it
  if so.
- **A refusal naming no line** (`push refused — the converted XML did
  not survive …`): not a problem with your text; tell the user to
  report it as a bug. Your text is unchanged.

It is always better to leave a step alone than to write text you are
unsure of. When text you were given disagrees in shape with this
document, copy the given text's shape.
