Numeric parameters between RPG programs

Good morning,
I have a problem in an RPG program, and I would like to know whether
exists a PTF to solve it or it is the correct behaviour.

In program 1 I have defined  a list of parameters to call to program 2,
one of these parameters in program 1 corresponds to a field from a
external described file, and its type is zoned (5S 0).
When I call the second program, it receives this parameter into a
program variable defined in D specs with the same type (5S 0), but the
contents of this variable is always garbage, and I receive a run-time
error in the first line that uses the variable.

I've noticed that including the field into a data structure in the first
program (without redefine it), or moving the field to a program defined
variable, the second program receives the value correctly.

So, I don't know if RPG doesn't support numeric fields as parameters
(although it seems that numeric program defined variables does), or a
type of 5S 0 in DDS is different to a 5S 0 in RPG, or I need to load a
PTF, or what. So, please I would appreciate any help to solve this
problem (of course, I don't want to move this field to a variable, or
create data structures just to avoid the problem)

I'm in V4R1, and it is an ILE program.

Thank you very much.
