RE: "If %scan(x:y)" is not valid???

["Bob Cozzi" <cozzi@xxxxxxxxx>]

The decision to use a procedure vs inline code is a tough one sometimes.
In this context, I would do a SETLL in the program and check %FOUND or
%EQUAL as the case may be.
But the criteria that the coder not need to know nor declare the file doing
the validation is also good justification for that 2-line procedure. If you
ever need to change that 2-line routine (to make it 3 lines, <g>) all you
need to do is change it in one location. Or, in your situation, if you ever
need to change the file name or do an additional check, all you have to do
is...

Those who don't use /COPY or don't use procedures because they "can't see
the code that's being run" are SEU users, typically, and also the same
people that are stuck working with those 5000+ line monolithic programs. So
yes, in that context, a single procedure won't help.

How about a two line subprocedure in a service
program.  I have many that do validation against a
file and only have a setll and a return %equal.  Then
any program that needs to do this validation can just
call VldRailroad(Road) and not have to include the
file in that program.  This simplifies program code
because each programmer doesn't have to know how to do
the validation.  Some validation routines are only the
two lines but some are much larger because the
validation is not so simple.
