Re: Calling a CL program from a free-format RPG program

[Alan Campin <alan0307d@xxxxxxxxx>]

dcl-pr MyCLProgram ExtPgm('CLPGM');
  PR_Parm1 Packed(7:2);
  PR_Parm2 Parcked(5:0);
end-pr;

MyCLProgram(Parm1: Parm2);

You do not need CALLP. Obsolete.

Other way is to make it s module.

dcl-pr MyCLFunction ExtProc(''CLMOD');
  PR_Parm1 Packed(7:2);
  PR_Parm2 Packed(5:0);
end-pr

MyCLFunction(Parm1: Parm2);

Either way you are just calling it like a function.

Also, I prefix all my prototype fields to with PR_ to indicate they are not
reall feilds, just documenation.
