Hi Istvan,

thank you very much for your prompt reply. ithen solves my problem 
perfectly. Apparently ithen was not in Csound 4.23 (syntax error) and it has 
not found its way into the current manual.

Regarding the \ in prints: Csound 4.23 did not work with a single backslash 
but of course two backslashes would have been sufficient and Csound 5 seems 
to be quite tolerant as to the number of backslahses. It accepts 1 to3 
backslahses, but not  more.

- Klaus
