Description

Use the while keyword to repeat a sequence of instructions as long as a condition continues to be true.

LiveCode evaluates the condition each time the loop repeats, at the top of the loop (before the statements in the repeat structure are executed). If the condition is false, the loop is skipped and execution resumes with the statement after the end repeat statement.

If the condition is already false when LiveCode reaches the repeat statement, the loop is not executed at all.
