The attachment contains a global search and replace I wrote and used a
long time ago.  It translates "ABCDEFGCDHIJKLCDMN" to
"ABXYZEFGXYZHIJKLXYZMN", and apart from the name matches your calling
semantics.

It's still in K&R C because it pre-dates the original C standard.
However, I see that the compiler I used did have some support for
'void'.  That was probably on SCO Xenix.
