Thanks to all.
I will be using a service program.

Are there any special issues with using a DSPF in a service program procedure?
I will be creating the program for V5R3.
I know that all I/O and file definitions are Globle in the module, but is there a downside to including it in an existing service program or should I create a separate service program?

I disagree.

It'd be easy enough to add a wrapper program if you ever needed external access to the functionality.

Just put the routine in a service program.

I have a function that will perform DB I/O and possible require a
display window.
This function will accept 1 parameter and return 1 parameter.
This function will be called from a number of programs.

Should I -
A. Make it a service program
B. Make it a bound modu[l]e
C. Make it a stand alone program called by others as needed.

Well, if there's any possibility of it ever being needed from some
program that (for whatever reason) HAS to be OPM, or of there ever being
a need to use it directly from a command line, then option C would make
these possibilities a lot easier to deal with.

Option B has the advantage of comparative simplicity, but if your
function is big, and called by a lot of programs, then it's also going
to be the bulkiest of the three options.

Really, it depends on the circumstances.
