Hello,

I do not find any real hint how to check an variable about its length. Like I want to check if the Variable is 30 chars long. But how? if someone have an short example I will be pleased.

Hi!

I made a small scriptlet for you:

Code: Select all

~Create 30 char variable~

Here is the human readable version of this code:

Code: Select all

// Create 30 char variable
Set Variable TEST to 123456789012345678901234567890
// See if longer than 30 chars
Parse String $TEST$ into Variables PART1 and PART2 (Split at position from start)
if Variable PART2 Equals 
 // Verified NOT longer than 30 chars
 Parse String $TEST$ into Variables PART1 and PART2 (Split at position from end)
 if Variable PART2 Equals 
   // Verified NOT shorter than 30 chars
   MessageBox: Verified!, This variable is EXACTLY 30 characters long!
 end
end
