Hello,

Show some input data (in hex) and the output you want from this process. Packed-decimal includes a sign. . .

what do You mean by unsigned PD ...
show the HEX representation like for example


Code:
00013579
0002468C


and guessing... You might want to transform it into
Code:
00002468
00013579


see Your previous post on dropping the decimal digits and use a bit of ingenuity ...

for example multiply by 10 into a 9 bytes field and use the first 8 bytes

Or "unsigned" as in Cobol sense, with an F instead of the C/D? If nothing standard for that, a bit of ingenuity along enrico's lines, but maybe with a binary as well. Could be more tricky, as who knows which sign will be retained?

I guess a dive into your manual is required.

well... for my interpretation here is a snippet

Code:
the code snippet

000007 //S1      EXEC PGM=SORT                                                 
000008 //SYSPRINT  DD SYSOUT=*                                                 
000009 //SYSOUT    DD SYSOUT=*                                                 
000010 //SORTIN    DD DISP=SHR,DSN=ENRICO.SORT.PS1                             
000011 //SORTOUT   DD DISP=SHR,DSN=ENRICO.SORT.PS2                             
000012 //SYSIN     DD *                                                       
000013   OPTION COPY                                                           
000014   INREC  BUILD=(1,8,PD,MUL,+10,TO=PD,LENGTH=9)                         
000015   OUTREC BUILD=(1,8)                                                   
000016 //*

well... for my interpretation, with no snippet.

Define right-most byte(s) (one or two, experiment) as BInary. Add 3 to it, to change X'?C' to X'?F'.

That's it.
