$while¶
Usage: $while(condition,code)
Category: loop
Implemented: Picard 2.3
Description:
Executes code
repeatedly until condition
no longer evaluates to True. For each loop,
the count is stored in the variable _loop_count
. This allows the count value to be accessed
within the code
script.
Note
The function limits the maximum number of iterations to 1000 as a safeguard against accidentally creating an infinite loop.
Example:
The following statement will set return
to “Echo… echo… echo…”:
$set(return,Echo...)$while($lt(%_loop_count%,2),$set(return,%return% echo...))
