Hmmm... Actually, you don't need to use EXTPGM on the prototype for the
main procedure -- but EXTPGM is needed if you're going to use the
prototype to make a dynamic call. If you're calling using another means
(such as the CL CALL command, a stored procedure call, call from another
language, call using CALL/PARM in RPG, etc) then you don't need the EXTPGM.
If you leave off the EXTPGM, the procedure name will have to match your
program name (or you get a compile error) but if named the same as the
program, it'll work. And, you can just to make bound calls, too.
starting in 7.1, you don't need the prototype (PR) at all (unless you
want to use it to make calls). You can just code the PI and leave off
the PR entirely.
