Thank you very much, Alan!

I am doing what you thaught I am doing. And this \edef is exactly what I
need. All is working now   :-))
By the way: where can I find information about these TeX (??) - commands
like \def, \edef, \gdef, ... and all the others that one can use in
LaTeX together with pstricks?

If you're doing what I *think* you're doing then you might try using 
\edef\x{\x 1 add}, but depending on what you're actually trying to do I 
can think of many different things that could be going wrong. If \edef 
doesn't solve your problem, please post a complete minimal example that 
demonstrates it.
