Anyone know the proper way to > accomplish this? You do it right the first time, wrong the second time. But it is not really necessary to save in a global variable, and you want stuff to get restored in any case. I'd use (defadvice compile (around cobol-compile activate) "Set ...." (let ((saved-start-process (symbol-function 'start-process))) (unwind-protect (progn (fmakunbound 'start-process) ad-to-it) (fset 'start-process saved-start-process)))) -- David Kastrup, Kriemhildstr. 15, 44793 Bochum
