Re: When to make a service pgm

All - 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.
