Hi ,

Can someone please help me out in identifying Upper case records and lower case records(First Byte need not be considered) using SORT functionality in JCL, write them into separate output files.

Field length = 20 Bytes

Look at the index of your manual for your SORT product. Give it a go.

If you get stuck, post what you've tried, and we can help.

Hi Billy,

I have used the below approach,


//SYSIN DD *                      
 SORT FIELDS=COPY                  
 INCLUDE COND=((2,1,CH,EQ,C'a'),OR,
               (2,1,CH,EQ,C'b'),OR,
               (2,1,CH,EQ,C'c'),OR,
               (2,1,CH,EQ,C'd'),OR,
               (2,1,CH,EQ,C'e'),OR,
               (2,1,CH,EQ,C'f'),OR,
               (2,1,CH,EQ,C'g'),OR,
               (2,1,CH,EQ,C'h'),OR,
               (2,1,CH,EQ,C'i'),OR,
               (2,1,CH,EQ,C'j'),OR,
               (2,1,CH,EQ,C'k'),OR,
               (2,1,CH,EQ,C'l'),OR,
               (2,1,CH,EQ,C'm'),OR,
               (2,1,CH,EQ,C'n'),OR,
               (2,1,CH,EQ,C'o'),OR,
               (2,1,CH,EQ,C'p'),OR,
               (2,1,CH,EQ,C'q'),OR,
               (2,1,CH,EQ,C'r'),OR,
               (2,1,CH,EQ,C's'),OR,
               (2,1,CH,EQ,C't'),OR,
               (2,1,CH,EQ,C'u'),OR,
               (2,1,CH,EQ,C'v'),OR,
               (2,1,CH,EQ,C'w'),OR,
               (2,1,CH,EQ,C'x'),OR,
               (2,1,CH,EQ,C'y'),OR,
               (2,1,CH,EQ,C'z'))
 


But I know this is not a comprehensive one, and there are 18 more characters left to be checked, which will involve a lot of 'OR' conditions. So I was checking if we have any specific functions in DFSORT to differentiate between uppercase and lowercase characters.

Thanks for taking your time to reply to my post.

Do you know that each record only has lower case / upper case after the first byte? If you do know so, why check every character? You can just compare the 2nd byte to 'A' -- if it is GE, you've got an upper case record and if not you've got a lower case record.

Since z/OS Version 2 Release 1 of DFSORT, new alphanumeric comparison tests are available.

Robert's suggestion is a good one. Just look at the first relevant byte. Use the data-type if available, otherwise the GT,C'A'
