in my experience of industry, the answer is a qualified No. It depends on
the size of the procedure, but typically something like Char2Hex would be
written from scratch every time. This happens for one or more of several
reasons, including:

1. the programmer doesn't know about the library routine and can't be
bothered to find out
2. the programmer wants to do his own version
3. the requirement is fractionally different for the new routine, so a new
one is written for fear of altering the old one
4. noone knows what the old one does
5. there is no library management
6. not written here syndrome
