Blank Variable

Robbyn · Post by **Robbyn** » Mon Mar 20, 2006 11:25 am

I have a variable that may contain spaces or text. The spaces are of an unknown length as is the text. I want to test if a variable has no text. How do I code for such a test an I see no trim or asci function?

Hi,

VBSTART
VBEND

//e.g.:
Let>val= some text and spaces
//Let>val=

VBEval>Trim("%val%"),val
If>{%val%=""}
//empty
Else
//has text
Endif

Try setting val to just spaces.
