AW: call rpg from clp with ds

Hi,

if you are on release V5R4 or higher it is possible to directly define a
data structure in CL.
This data structure can be passed as parameter to RPG.

DCL VAR(&MYDS) TYPE(*CHAR) LEN(7)
DCL VAR(&MYSUBFLD1) TYPE(*CHAR) STG(*DEFINED) LEN(3) DEFVAR(&MYDS)
DCL VAR(&MYSUBFLD2) TYPE(*CHAR) STG(*DEFINED) LEN(4) DEFVAR(&MYDS 4)

As Alan already pointed out only a pointer to either the data structure or a
character field will be passed.


Mit freundlichen Grüßen / Best regards

i am not sure why not. RPG just receives a pointer to the data. You can
simply define a type as two fields and receive that it should be fine.

d TD_Receive...
d ds Qualified
d Template
d Field1...
d 3a
d Field2...
d 4a

p MyProgram...
p b
d pi Extpgm('APGM')
d InFields...
d LikeDs(TD_Receive)
d Const
/Free

Afield = InFields.Field1;
Bfield = InFields.Field2;

Hi,

If a parameter to an rpg4 pgm is a data structure with 2 zones 3A and 4A,
can I call it from a clp like call mypgm(7A)?

Thanks
