RE:Skip first n records and last n records in a file
You can easily skip records from top by using SKIPREC command. But for skipping records from bottom, you may consider the following
approach
-Add a sequence number atthe end of the file(using SEQNUM,7,ZD as the sortcard
-Sort the file by the sequence number in descending order, which will bring records from bottom to top.
-Now use skiprec to skip n records
-Sort the file again in ascending order of sequence number, to bring it back to original order.
-Remove the sequence number using INREC/OUTREC
