Spot the difference

Hi group,

I am having a very weird problem in one of my programs, when using the
QMHSNDPM API.

This is a snippet from the actual code (on V4R3M0, in case it matters):

 D  Msglen         S              9B 0
 D  Msgstk         S              9B 0
 D vApiErrDs       ds

 D  vbytpv                       10i 0 inz(%size(vApiErrDs))
bytes provided
 D  vbytav                       10i 0 inz(0)
bytes returned
 D  vmsgid                        7a
error msgid
 D  vresvd                        1a
reserved

 c*                  Parm      '*INFO'       Msgtyp           10

 c*                  Parm      '*'           Msgpgq           10

 c*                  Parm      0             Msgstk

 c*                  Parm      *blanks       Msgkey            4

 c*                  Parm                    vApiErrDs

When I use the normal call, the message is displayed on the screen, but
when I use the prototyped CALLP, it only shows in the joblog.

Am I missing something?  I already tried playing with the message type
entry and the call stack entry, but this does not make a difference.

Any help would be highly appreciated.
