Edit a Spool file before printing

Here is something I wrote in a hurry:

   Pgm                                                      
                                                            
   Dcl        var(&cmd) type(*char) len(2000) +             
                value('?ChgSplFA ??job() ??splnbr()')       
                                                            
   Call       pgm(qcmdchk) parm(&cmd 2000)                  
                                                            
   ChgVar     var(&cmd) value('?CpySplF tofile(spool198)' + 
                *bcat %sst(&cmd 10 1990) +                  
                *bcat 'ctlchar(*fcfc)')                     
                                                            
   Call       pgm(qcmdexc) parm(&cmd 2000)                  
                                                            
   WrkDbF     spool198                                      
   OvrPrtF    file(qprint) pagesize(*n 198) ctlchar(*fcfc)  
   CpyF       fromfile(spool198) tofile(qprint)             
   DltOvr     qprint                                        
                                                            
   EndPgm
