Does that mean the file is ASCII or UTF-8 or UTF-8 with Byte Order Mark (BOM)??

Does the file contain any TAB characters or CR/LF sequences? 

I think they are trying to check the value of a text field, rather than a file.... Christine, there are not any built-in SBM AppScript functions for this type of check. However, AppScript is based on VBScript 4.0. So, I would suggest googling for an vmscript function that does this check. I would guess that you could find some good example out there.

Arg!  Mis-read "Field" as "File".  Rented brain.

Christine: Is this on a Transition form?  It would be relatively easy with JavaScript to strip any character in a Text field that isn't in the range of decimal 32 (0x20; ASCII SPACE character " ") to decimal 126 (0x7E; ASCII TILDE "~").

The JavaScript could also confirm that a Text field only contains Alphanumeric chars without modifying the field.  What do you want to do with the result of that evaluation?

Hello, thanks for your answers. This is a script after a transition.  If the field is not an alphanumeric field, I stop the transition and the user must change the field value. It's not javascript or VBscript, it's teamscript. It's because it's difficult for me to find information in the web.
