I tried to code the PR/PI in my first RPG and it says I can't return a
value. Do I need something different? Sorry I'm so vague. I'm still not
where I need to be on procedures/service programs, etc.
In order to return a value, you need to tell the procedure interface
(and prototype) that. Here is an example of a procedure that takes a 10
character 'date' and converts it into an 8 digit number. The place
where we define what gets returned is on the PI spec; here it's '8s 0'.
The actual /value/ that gets returned is in the return statement (here,
unimaginatively called retVal).
* convert 'yyyy-mm-dd' to yyyymmdd
p date10to8 b
d date10to8 pi 8s 0
d date10 10a const
...
d retVal s 8s 0 inz
...
return retVal;
p e
You'd do something similar with your 'return the next number' procedure.
