MAINFRAME - TIP OF THE DAY : Sometimes it might be helpful to see only 1 or a few records in HEX (rather than the entire file w/ HEX ON). When VIEWing or EDITing a file use the line command HX to show that line in HEX. To show 3 records, enter HX3. To turn the hex off enter HX (for 1) or HX3 (for 3). Or in the Command area, enter HEX OFF.

Hi,

My requirement is -
In my JCL step I need to find the total count of records in input file, if its more than 50K then I won't be running further steps in the JCL, else I run them.

Could you please help me with this?

Quite simple,

Assuming your input LRECL 80 bytes

use the below sort code
Code:

//SYSIN DD *
  OPTION COPY,STOPAFT=50002
  INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:SEQNUM,8,ZD)),
        IFTHEN=(WHEN=(81,8,ZD,GT,50000),OVERLAY=(89:C'A'))
  OUTFIL INCLUDE=(89,1,CH,EQ,C'A'),NULLOFL=RC4 


This step will set return code 0, when you have records more than 50K and set 04, when it is less than or equal to 50K.

now you need to handle other steps condition to execute when RC is 04.

Thanks
Magesh
