Re: Prototypes and /COPYing

["Nelson C. Smith" <ncsmith@xxxxxxxx>]

Jim,

While I break up my procedures themselves into subject-related service
programs (like your math procedures), I have found it simpler to just put
all the prototypes into a singe copy member (called Prototypes, strangely
enough) and then just use the Define and Undefine compiler directives to
include only the prototypes desired in any one given program.   If you use a
procedure in the program and forget to include the compiler directive for
it, the compile listing will give you a 7030 error and you will see your
mistake quickly.

Also, all those service programs are listed in the same binding directory,
so there is only one thing you have to remember on the compile commands,
too.  I believe in keeping it as simple as possible.
