We have been constantly improving our batch window by implementing the
following available technologies:
1. SMS SMB and data compression on some of our VSAM files
2. System determined blocksizes on sequential files
3. BUFNO on some input files
4. Constantly improving our access to DB2

That sounds logical. Thanks, Jim!

Nowadays, oncall programmers are not expected to solve problems. They are

Judicious use of DISPLAY statements can tell the programmer, for example,
exactly which record to pull from the input file. Yes, you can also figure
