Sample DCL code for simple client-server task-to-task comms

by sampsa＠mac.com

Thanks for all the help guys - I think I'm pretty close to having all the stuff I need for my little client server project.

IIRC, your procedure must open SYS$NET, no matter what it will possibly send through it, even if it will not send anything back, because it is the opening of SYS$NET that triggers the dispatching of the DECnet connect-confirm message back from the target node to the originating one. Just try a procedure that does a five minutes wait, but does not open SYS$NET, and you'll see that the network will time out with an error way before five minutes (and your procedure will be stopped). Then simply add the open of SYS$NET before the wait command and you will see that it will work whatever time you chose for the wait, i.e. it will not time out, because the connection will be opened and confirmed both sides and both ways. IIRC it's not even necessary to explicitly send something thru SYS$NET to confirm the connection, just open it. HTH, :) G.

You'll understand when you come to visit. Yup. From the pictures I've seen, you've got quite a few racks. ;) Speaking of 1Us, I have a 1U sitting on top of your ES40. Quite a size difference! ;) You're gonna love the es40 sitting in the living room waiting patiently for you in the winter. ;! She'll definitely keep a room warm. You get the one with two drive cages, too. Plus! FibreChannel cards! Schweet! When you come to pick her up and do the trade, you can pick if you want any of the PCI cards from my ES40. Several of them I will never use. ;) I do need to devise a better way to keep the hard drives plugged in though...currently have them propped up with screwdrivers...need something to support the full-height drives that predate the ES40. ;) -Dave -- Dave McGuire, AK4HZ New Kensington, PA
