Re: Variables in service program

In a service program the global variables are shared by all the
functions, for sure in the same call.

Will they keep their value if a RPG program calls a different
function? It seems yes, but always?

If other job calls a function, will it have its own values?

My goal is to write several functions and use the values of previous
calls. It will work if I pass the values as parameters, can I omit the
parameters, and still have the values?

In the same job and in the same activation group, yes, the service
program's global storage retains its values. Service procedure local
storage initializes with each call -- unless the STATIC keyword is used
for particular local variable(s). Different activation groups and
different jobs would have to employ some other mechanism for shared
storage.
