Arrays of Structures as a parameter in V5R1

Hi,

Looking for suggestions for ways to program arrays of structures (which also have arrays) as an input parameter. Program will be called from an external Java program using pcml. Unfortunately we are on V5R1 and the project deadlines may not allow an upgrade to V5R2 before implementation.

Within the RPGLE program the input structure looks something like this:

SKU                     15,A
num1                    5,0
SKU Size 1              15,A
Qty for Size 1          7,0
Date for Size 1 8,0
.
.
.
SKU Size 36             15,A
Qty for Size 36 7,0
Date for Size 36        8,0

This whole structure will be repeated up to 30 times in one call to the program.

There is also a return code at the end of all of this.

Partial list of the proposed pcml call looks something like this:

<struct name='availreply' >
        <data name="size" type="char" length="XX"/>
        <data name="availabilityQty" type="<packed or zoned>" length="XX"/>
        <data name'"date" type="<[acked or zoned>" length="8"/>
</struct>

<struct name='stylerequest' usage='inputoutput'>
<data name="styleNumber" type="char" length="XX" usage='input"/>
<data name="reply" type="struct" struct="availreply" usage="output" conunt="36"/>
</struct>

<program name="pgm1" path="/QSYS.LIB/.../pgm1.pgm">
<data name="request" type="struct" struct="Stylerequest" count="30" usage="inputoutput"/>
<data name="returnCode" type="char" length="XX" usage="output"/>
</program>

The call will be requesting from one to 30 SKUs at a time.

So far, I am not seeing any way to do this other than one huge input parm with all the fields listed individually. Perhaps a list of 30 structures, or would that be 30 parameters?

Thanks for the help.
