Expat, i couldn't get you from Rec Format and its length.
only i need to replace the starting 10 bytes from ZEROES.
SORT FIELDS=(1,10,CH,A)
OUTREC FIELDS=(1:1,10,123X)
i used the above defined sortcard, but it gives an spaces.
can you help me out how to define zeroes.
Thanks,
Ank |

Hi,
you say you want to replace the first 10 bytes with zeroes, but your output shows only 8 zeroes.
Anyway, this will replace the 10 first bytes
| Code: |
OUTREC OVERLAY=(1:C'0000000000')

You can use C'0' for a character zero or nC'0' for n character zeros.
If you want to overlay the first 10 bytes with character zeros, you can use:
| Code: |
OPTION COPY
OUTREC OVERLAY=(1:10C'0')
|
You can use a SORT statement instead of OPTION COPY if appropriate.
If that's not what you want to do, then you need to explain more clearly what you want to do with a good example of your input records and what you expect for output. |
