Essentially, what you're describing is what I call a "code
snippet" and I put such things in a copybook. Thus, they would always be
used in-line no matter how many times they were included in the program
source. As an alternative, to reduce program size, you can wrap the same
copybook with subroutine code in order to formally "call" it from multiple
places in the program. Thus, the same copybook can serve in two different
ways.
However, I do understand the "loss" of being able to maintain the
code snippet in the same source code member. The code copybook would have
to be maintained as a separate member. The alternative is to make the
code snippet into a macro and leave the macro source in the main program
source so that they can be maintained together in a single member.
Sincerely,
Dave Clark
