RE: File and Program field definition

Don't you just love RPG.  Since math is more efficient in Packet form, the
RPG compiler brings the file specs into the programs converting all number
to packed form.  While the input buffer is Signed Numeric, it gets mapped to
a Packed field.  Insert an externally described data structure and your
problems will disappear.  The data structure will force the field to remain
Signed Numeric.  By the way, the fields defined in a PR statement do not
exist unless defined somewhere else.  They are just place holders for the
compiler to resolve the interfaces at compile time.  The following will also
work.

54+D GetCoupon       PR                  extpgm('ZED005')
55+D                               11S 0
56+D                                5S 0

I've got something weird.

1. There is an external program that is defined to the calling program
through procedure prototype as:
54+D GetCoupon       PR                  extpgm('ZED005')
55+D PLUParm                       11S 0
56+D ValueParm                      5S 0

*** note PLUParm parameter.

2. There is a file that has PLU defined as:
0012.00      A            S01PLU        11S 0       COLHDG('COUPON PLU')

3. In the program I call procedure as:
0186.00 C                   CallP     GetCoupon(S01PLU:CouponValue)


4. Compiler gives me an error:
*RNF7535 30      1 The type and attributes of the parameter do not match
those
                   of the prototype.

5. Looking at compiler listing I see that S01PLU field is defined as
packed:
0008.36          S01PLU            P(11,0)

6. This field is defined ONLY in the file and in the program it gets only
referenced.

Does anybody have an explanation for this phenomena?
