Passing parms in a submitted call from a RPG programm

Hello all,

I hope there's anybody who can help me with the challenge. Picture this:

*========================================================================= 

* (Externe) Prototype Definitions 
*=========================================================================
  // Submit clear  
D QCmdExc         PR                  ExtPgm('QCMDEXC')  
D  cmdString                    90A   Const Options(*VarSize)  
D  cmdLen                       15P 5 Const 

*========================================================================= 
 
* Variabele declaration  
*========================================================================= 
 
D cmdString       S             90A 
D cmdLen          S             15P 5 
D pressNum        S              2A   Inz(*Blanks) 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Main processing
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
*=========================================================================
* SrA999 Clear Optalex_Tx file with a submit 
*=========================================================================
C     SrA999        BegSr 
   /Free  
    pressNum=%subSt(trgBufIn.file : 5: 2); 

    cmdString='SBMJOB CMD(CALL PGM(*LIBL/POXTX0CL) PARM(pressNum))'; 

    CallP QCmdExc(cmdString: %Len(cmdString));
/End-Free 
C                   EndSr 
****************** End of data 
********************************************

When I catch the matching variable in the CL program POXTX0CL the value = 
'pr". If tried the pass the value hard coded as e.g. '07', but when 
compiling the compiler gives a "*RNF5377 20      1 The end of the 
expression is expected. " on the quotation marks. Changing the data type 
to numeric has also no influence, the received value is blanks en the 
program comes back wit a decimal data error. The only thing I haven't 
tried is a compile time array with completely valued command strings, but 
I don't think that that's the solution for this problem.

I'll want to thank everybody in advance for thinking with me.
