MODS in subprocedures

I sometimes (but not every time) have this problem.

I am returning a pointer to a MODS in a sub procedure.  Sometimes the data
is valid - what I expect - and sometimes the data is garbage.

Here's a bit of my code (they are SQLRPGLE members)

H nomain
 *------------------
D getResources    pr              *
D  pr_rsctyp                     1    value
D  pr_key                        9  0
D  pr_rows                       5  0
 *------------------
P getResources    b                   export
D getResources    pi              *
D  rscType                       1    value
D  key                           9  0
D  rows                          5  0
 *------------------
D resourceDS      ds                  occurs(dsSize) based(p_rscDS)
D  resource               1     10
D p_rscDS         s               *   inz(%addr(#p_rscDS))
D #p_rscDS        s            100

C                   clear     *all          resourceDS
C** build the data structure here **
C                   return    p_rscDS

This is a snip from the calling subprocedure:
D getResources    pr              *
D  pr_rsctyp                     1    value
D  pr_key                        9  0
D  pr_rows                       5  0
D p_rscDS         s               *

C                   eval      p_rscDS = getResources('T':key:rows)
C
C                   for       i = 1 by 1 to rows
C     i             occur     resourceDS
C                   endfor

The address for p_rscDS is the same.  But the value contains garbage data.

Can anyone see what am I doing wrong here?

Thanks for your help,

Phil
