we have a VB VSAM file with RECORDSIZE(2048 32760).We have a requirement to delete records that have '07' in the 350th byte.

We are trying to get this done thru an OMIT COND=(354,2,CH,EQ,C'07) into a flat file and then Delete/Define the VSAM file and put the remaining recs back.

However we find that there are records which are less than 350 in length and for those SORT fails.

Is there any option in DFSORT to skip the records that are less than 350 bytes and only apply the OMIT COND on the remaining records.

I'd suggest:

Code:

   OMIT COND=(1,2,BI,GE,+355,AND,354,2,CH,EQ,C'07)


That will ensure that records which do not have the bytes in 354-355 that you are testing for are kept. This is probably more efficient than using VLSHRT or VLSCMP.
