RPGIV Fans and Experts,

Is the following a bug, feature or?  I have found that when a parameter is 
declared as *VARSIZE and is an array opdesc will not work.  Passing a 
datastructure over the array works.

     DPrc              PR            1A   OPDESC
...
     DFldLst           DS
     D Fld                           10A   DIM(4)
...
     DPrc              PI            1A   OPDESC
     D Fld                           10A   DIM(3275)                            
Field names.
     D                                     CONST OPTIONS(*VARSIZE)
...
The following works:

     C                   EVAL      ErrFlg      = Prc(FldLst)
...
The following does not work:

     C                   EVAL      ErrFlg      = Prc(Fld)

Thanks,

David Morris
