Re: calling RPG ILE with parameter list from MI

Yes, James is exactly correct. If the RPG program is accepting just ONE parameter (no matter what size), you must define the Operand List in the MI program the same way; that is, with just one element (the pointer to the structure).

In the MI program, you can subdivide the structure using "subvariables" [to coin a term] with the DEF() POS() keywords; very similar to a data structure in RPG. This is *Defined storage (we can now do a similar trick in CL, after all these years).

The MI language has certain limitations about INITializing objects. I remember that when you define an operand list, the variables it refers to must be defined previous to the operand list itself, in the MI source. Perhaps the same is true with space pointers; I am not sure. At any rate, the translator will catch you if you do it wrong!

Hope that helps,

Hello all,
I am trying to call an RPGLE pgm from MI passing parameters to it.

Well, for one thing, if you're passing two parameters AS SEPARATE
PARAMETERS, shouldn't you be accepting them that way?

Also, I always define the field first, then the space pointer INITed to
it. I've never heard of it working the other way around.
