do
Type
command
Summary
Executes a list of statements.
Syntax
do <statementList> [in caller]
Description
Use the do command to execute statements in a container, or to execute a statement that consists partly of a literal string and partly of a container or the return value from a function.
Using the do command is slower than directly executing the commands, because each statement must be compiled every time the do command is executed.
When the do statementList in caller form of the do command is
used, the statementList is evaluated in the context of the handler
where the do command appears.
To see how to create a numbered set of variables see the dictionary entry for the local command.
You can use the do as alternateLanguage variant of the do command to evaluate a statementList written in a non-LiveCode programming language.
Parameters
| Name | Type | Description |
|---|---|---|
statementList | A LiveCode statement, a container with one or more statements, or a string that evaluates to a statement. |
Examples
do "go next card"
do "put" && tNewValue && "into tNumberOfRecords"
-- If tNewValue is 3, this would become "put 3 into tNumberOfRecords"
do "select" && line 3 of field "Objects"
