thank you, it worked. i even knew this print for displaying output from a proc, but i never thought that print(p) would do anything else but print that plot structure, i thought print was a text command. anyhow, i kind of understand that output to the worksheet is suppressed in certain inner scopes. but why is writing to files prevented too? how does maple even know which commands to do and which to ignore? does it keep a list?

and are you saying that someone should write this into the faq or that it's in the faq already? if the latter is the case it would be nice if you pointed me there. i did not find any solution when i searched things like "display in proc".
