Amazingly enough, I worked at a shop a couple of years back (non profit health care management) that still used these techniques. IBM nearly choked when they bought a new AS400 and wanted to load it up with six 8MM and two 1/2" tape drives so that they could process _four_jobs_ at the same time. Tape to tape operations to merge transactions into the "database". Stat reporting often took as long as five or six hours to just read through a tape. YUK! Just goes to show how resistant to change some folks are. Just a junior (pseudo) geezer... ;) Eric A DeLong ericadelong@pmsc.com ______________________________ Reply Separator _________________________________ Subject: RE: what is unclear about 01 02 03 Author: <MIDRANGE-L@midrange.com > at INTERNET Date: 5/2/98 11:15 PM >These are easy. How about matching record indicators (M1 - M9 and MR) or >Halt indicators (H1 - H9)? Ah! Matching Record Logic... Imagine it's just a Big Merge of records into the selected key sequence. And the H1-H9 indicators. Useful as traps in your logic when you're too lazy to code the necessary trap. Simply insert a Halt Indicator and have your program come to a screeching halt when something (like a disk read or write) fails to complete properly. --Paul E Musselman PaulMmn@ix.netcom.com +--- | This is the Midrange System Mailing List! | To submit a new message, send your mail to MIDRANGE-L@midrange.com. | To unsubscribe from this list send email to MIDRANGE-L-UNSUB@midrange.com. | Questions should be directed to the list owner/operator: david@midrange.com +--- +--- | This is the Midrange System Mailing List! | To submit a new message, send your mail to MIDRANGE-L@midrange.com. | To unsubscribe from this list send email to MIDRANGE-L-UNSUB@midrange.com. | Questions should be directed to the list owner/operator: david@midrange.com +---
