SUBSET is supported in SyncSort for z/OS 220.127.116.11 (SYNCTOOL release 1.6.2). When you say that the code is not working, what error message are you getting? If it is a syntax error, I suspect that you are running an earlier release of the product.
Thanks for the suggestion Alissa. But Iam working for a SW Company and i do not have any rights to do any upgradations or installations. I have to make use of what i have. So it would be helpfull if u suggest me any alternative for the above CODE.
If you use the sort to simply "copy" the file and direct the output of the copy to a DD DUMMY, the output will show the record count. . .
"Very large" has different meanings in different environments. We'd probably all agree that a billion records is very large. How about 1million or 10 million? Some places have no files that big while 100 million is about average for several of the processes i support. . .
