 Return more than one parameter from a subprocedure
Subprocedure
I want to return Name, DOB and Place of Birth from a Subprocedure. Is it possible to return more than one parameter at a time? Any method other than using the same parameter as input and output?

Return a data structure (i.e., a DS).

By returning a value, you are creating a function which by definition will always return "a value". Not two values or three values.

However, the value can be a structure; and you can use the single structure to carry a set of subfields.

For what you’ve described above and assuming you are going to use a service program can you not just define the procedure interface with a character return value long enough to contain all 3 pieces of information as fixed-length entities, and then split them back out again after the subprocedure call?

I will typically define procedures to return a boolean – successful/unsuccessful
With input (Constant) paraamerters and output parameters (not constant) and error parameters (*OMIT) so they can be omitted from the list.
