Free Memory for Pasting 64 chars to Clipboard

[Mike Trader]

Ive been reading Poffs about pasting text to the clipboard. I see some great examples that i think are more complicated than I need for pasting a short file name to the clipboard.

Do I need to free enough memory for this first?
Does anyone have a really simple example available for pasting text from a PB app to the clipboard (for pasting into the editor later)

Kind Regards
