You can write a VB Application that can be called via RUNRMTCMD and pass
it the value you want to copy/paste. 
Another alternative would be something like our iSeries Office
Integrator software. 
Example CL command to set the clipboard data:
OFCRUNPC CMD('This is test data') OPTION(*CLIPSET)

subject: Can I use an F-key to fill the PC copy/paste?
I would like to have some means of selecting a customer and have the 
selection (F-key, Subfile option, whatever) fill the copy/paste so that 
that name & address can then  be pasted in the predefined format into a 
PC screen.
Is that possible?  Did I explain it clearly?
