While (command)

WHILE <expression>

Use this command to repeat a sequence of statements while a certain condition exists. The expression used must return a Boolean true or false value. You must end the group of statements being executed with the ENDWHILE command. For example

# Test to see if the 10 files test1.zip to test10.zip exist, then do some action
SET $Count = 1
SET $File = "Test"
WHILE $Count <= 10
IF FileExists($File + "$Count" + ".zip")
commands ...
ENDIF
$Count = $Count + 1
ENDWHILE

Notice the use of the "$Count" (using double quotes) in the FileExists expression. By surrounding the Numeric variable $Count in double quotes, you are typecasting it on the fly to a string value. This enables the expression to work because you can't just add a numeric variable to a string variable as in $File + $Count
