Re: Calling similiar (overloaded) procedure that has *nopass *omit in the parameter

Well not quite as bad as I thought...at least you can pass the omitted
parm through without having to check it

select;
when %parms() = 3;
Proc2(parm1:parm2:parm3);
when %parms() = 2;
Proc2(parm1:parm2);
other;
Proc2(parm1);
endsl;

Note the above uses a 10a CONST parm1 for ease of testing...your
procedure will be more complex.

You could also simplify procedure handling in Proc2, remove the
*NOPASS and code the above as

select;
when %parms() = 3;
Proc2(parm1:parm2:parm3);
when %parms() = 2;
Proc2(parm1:parm2:*OMIT);
other;
Proc2(parm1:*OMIT:*OMIT);
endsl;
HTH,

There isn't an easy way...since RPG doesn't offer true null support...

Proc1 will be (big) select statement that determines which way to call Proc2...

Parm1 is also going to be problamatic since it's not defined CONST or
VALUE...are you really using it for output?

Assuming that proc1 is an overloaded procedure of proc2.  Proc1 contains no
business logic.  All it does is converting the parm1 into alpha and calls
proc2.  As you can see, both parameter 2 & 3 in proc1 & proc2 are *nopass
and *omit type parameters.  Can someone give me a pointer on best approach
on calling proc2 from proc1?



D proc1           pr
D  parm1                        10p 0
D  parm2                        10    options(*nopass :*omit)  const
D  parm3                        10    options(*nopass :*omit)  const

D proc2           pr
D  parm1                        10
D  parm2                        10    options(*nopass :*omit)  const
D  parm3                        10    options(*nopass :*omit)  const
