Re: saving status inside multiple calls to service program

It's definitely possible.

Any variables that are to retain their values must NOT be in automatic storage, though. In RPG, that means coding the STATIC keyword on them, or coding them as global variables. (Or parameters, I guess.)

D IsLoaded s 1n static inz(*off)
D loadedValue s 10a static
/free
if not IsLoaded;
chain 123 SETTINGS;
if %found;
loadedValue = SETTING;
isLoaded = *on;
endif;
endif;
return loadedValue;

Is it possible to code a procedure in a service program such that it can
retain values from one call to the next? I haven't been able to accomplish
this and I could cut down on some logic if it can be done.

An example would be: if a flag has not been set (procedure never called
before), retrieve some static values from a database. If the flag IS set,
those values are already set and available for use in the current call to
the procedure.

Thanks
