issue with Strip

[Ylenia Curci]

Hello,

I am trying stripping some punctuation of a long string variable by using the following code

strip text, of (".!?:;~{[(-_\/^)]}") g(textbis)

and I get the following error

str164211 invalid variable name

Any hint?

Thank you.

It works perfectly with shorter variable, so I guess the answer to my question is that strip does not generate long string, isn't it?
