My sortcard looks like this,
Code:

  JOINKEYS FILES=F1,FIELDS=(15,25,A,50,2,A,65,8,A,83,4,A)             
  JOINKEYS FILES=F2,FIELDS=(15,25,A,50,2,A,65,8,A,83,4,A)
  REFORMAT FIELDS=(F1:1,860,F2:1,860),FILL=X'FF'                 
  JOIN UNPAIRED                                                 
  SORT FIELDS=(15,25,CH,A,50,2,CH,A,65,8,CH,A,83,4,CH,A)
  OUTFIL FILES=01,INCLUDE=(861,1,BI,EQ,X'FF'),OUTREC=(1,860)     
  OUTFIL FILES=02,INCLUDE=(1,1,BI,EQ,X'FF'),OUTREC=(861,860)     
  OUTFIL FILES=03,INCLUDE=(1,1,BI,NE,X'FF',AND,861,1,CH,NE,X'FF'),
                            OUTREC=(1,24,....)


My file lengths are 860 bytes each... Do I need to add sort work files? My input may have upto 100,000 records. Will a Cobol program be a better option?
Also, if I include a IFTHEN clause in my outrecs, then what?

Are you facing any space issues? If so then have the work datasets allocated.

What are you trying to do here...? The question is not clear!!
