1) what is the difference between OPTION COPY and
SORT FIELDS=COPY and what does option keyword do?

2) I wanted to exactly split the file into two.

If the i/p file has odd number of records, how will you 'split exactly'?
This was discussed many times. Please search the dfsort forum.

Hint: Search word 'split'.

Both invoke DFSORT's copy function. The only difference (which usually doesn't matter) is that SORT FIELDS=COPY can be overridden by another SORT statement whereas OPTION COPY can't.

Take a look at the "Split a file to n output files dynamically" Smart DFSORT Trick at:

http://www.ibm.com/servers/storage/support/software/sort/mvs/tricks/

and see if it does what you want. If not, then you need to explain exactly what it is you want to do.
