MV is working....had to add -f to it.
Is there an easy way to (Programmatically) get rid of the "END OF PROGRAM" message every time I execute the sh or a command please ?
thanks

You can do something very similar in straight MPE with:-
PURGELINK targetfile
COPY sourcefile, targetfile
I used to do this a lot, generally with both commands within a user
command, to minimise the window for failed access to targetfile during
the process.
I guess the 'mv' approach might be completely atomic, and so close this
window completely, though?
