AW: Exception handling with QCMDEXC

[Werner Noll <werner.noll@xxxxxxxxx>]

Rob,

some time ago I did some "research" on this problem. I created a procedure
called YRCVPRVMSG (Receive previous message). An example for the usage:

D yRcvPrvMsg      PR                   Like($GEMDS)
D $GEMDS        E DS                  ExtName(YGEMDS) Qualified

   p$CmdStg = 'CHKOBJ OBJ(''HUGO'') OBJTYPE(*PGM)'; 
   CallP(E) QCMDEXC(p$CmdStg:%len(p$CmdStg));       
   If %error;                                       
      // Call Procedure   
      $GEMDS = yRcvPrvMsg();                       
      // Display Error Message
      If $GEMDS <> *blanks;                                             
          r$RtnVal = yDspMsgWdw($GEMDS.MsgId:$GEMDS.MsgF:$GEMDS.MsgFLib: 
                     $GEMDS.MsgDta);                                     
      EndIf;                                                            
   EndIf;                                             


The code of the procedure yRcvPrvMsg is:

 yRcvPrvMsg      B                   Export                     
                                                                
 yRcvPrvMsg      PI                  Like($GEMDS)               
                                                                
 r$GEMDS         S                   Like($GEMDS)               
 #MsgKey         S              4A                              
 #StackCnt       S             10I 0                            
                                                                
/free                                                           
 $GEMDS    = *blanks;                                           
 r$GEMDS   = *blanks;                                           
 #MsgKey   = *ALLx'00';                                                 
 #StackCnt = 1;                                                         
                                                                        
 QMHRCVPM($RCVM0200:%size($RCVM0200):'RCVM0200':'*':#StackCnt:'*PRV':   
          #MsgKey:0:'*SAME':$APIErrDS);                                 
 If $GEMDS.MsgId    = 'CPF0006';                                        
    #MsgKey = $RCVM0200.MsgKey;                                         
    QMHRCVPM($RCVM0200:%size($RCVM0200):'RCVM0200':'*':#StackCnt:'*PRV':
             #MsgKey:0:'*SAME':$APIErrDS);                              
 EndIf;                                                                 
                                                                        
 If $APIErrDS.ByteRtn = *zeros;                                         
    $GEMDS.MsgId    = $RCVM0200.MsgID;                                  
    $GEMDS.MsgF     = $RCVM0200.MsgF;                                   
    $GEMDS.MsgFLib  = $RCVM0200.MsgFLibU;                               
    $GEMDS.MsgDta   = %subst($RCVM0200.MsgText:1:$RCVM0200.LenRtn);     
 EndIf;                                                                 
                                                                        
 r$GEMDS = $GEMDS;                                                      
 Return r$GEMDS;                                                        
 /end-free            
                      
P yRcvPrvMsg      E   
                      
There are some company individual specials inside it (e.g. $GEMDS). But the
usage of the QMHRCVPM can be reproduced by my code.
The procedure works, but I didn't implement it yet in applications.
Hope it can be proposal for you.

Werner Noll

Betreff: Exception handling with QCMDEXC


I have a routine that executes a command using QCMDEXC.  I want to check 
the results of the command.  I use the PSDS to find the results.  However 
from the joblog I get:
CALL TSTEH01 
CPD0032-Not authorized to command KICKBOOTY in library *LIBL.
CPF0001-Error found on KICKBOOTY command. 
CPF0006-Errors occurred in command. 
And what appears in the Exception message field from the PSDS?  Just 
CPF0006.  I was hoping for the CPD0032.

Tried using system(), but that just showed the CPF0006 message also.

Suggestions?

End goal is to ENDSBS and I want to see the plethora of messages displayed 
on the help for ENDSBS.  I'll process it differently depending on whether 
or not the subsystem is running, etc.
