requirement:
in certain byte, contain the offset, check the value in the offset, if it contain the value, copy to output

e.g.:
5th byte is the offset, the record will be included if the value in the offset is x'0F'
Is it possible in DFSORT?

input

videlord,

Do you array of offsets you need to check or is it a fixed position? From your sample data it looks like it is an array

so try this

thanks, kolusu.

The offsets are not fixed positions.
the record is VB format, record lenght can be more than 30k.
And in the sample input, all other bytes are ingored (simply code x'00'), they can be anything in real data, the "OR" doesn't work.

What format is the offset is a 1 byte binary or what?

SMF data is one of the example.
The offset can be n bytes binary, it doen't matter how many bytes. (usually it's 2 bytes)
