RE: Unclassified RE: [U2] Quick question on Longnames
Yeah, and get rid of Type1 for dirs in uvhome while you're at it (catdir, APP.PROGS, BP, INCLUDE, etc.). And default file types for &SAVEDLISTS&, &PH&, &COMO&, &HOLD& should be Type19 when they get created, too.

Re: [U2] Quick question on Longnames
You know, some days the brain just doesn't work very well. Since I probably caused confusion to some of the newer folks with my previous blathering, let me point out that I answered the question of longnames by talking about the Type1 vs Type19 issue. Smooth, real smooth. Longnames handles the mapping of UV filenames with length > 14 chars into a Unix file name of only 14 characters (those 000 and 001 files). The VOC file record ID will have the full name with the truncated and numbered file names used in fields 2 and 3 of the F pointer. Even with longnames on, type 1 files still break down into subdirectories. My preferred usage: LONGNAMES ON Type1 files == evil Type19 files == good Sorry 'bout the flub. -- Regards, Clif ~~~ W.

[U2] Quick question on Longnames
Hola all - Background: We're coming up to speed on a Universe 9.5 (on Irix 6.5 on a Challenge-L vintage 1994 or so, pity us) system that's been largely unmanaged for the last 4 years or so, so there's not a lot of institutional knowledge here. We're planning to migrate to RedHat AS3 and are working with the 10.1.4 release in testing. One of our programmers asked what the consequences of choosing longnames=on in the install are. My understanding from the administration manual is that it will only impact us should we decide to go back to a system that doesn't support longnames, which I can't foresee happening, but that transitioning up shouldn't be problematic even though we already have a couple of truncated/renamed filenames in the current production system. I assume they'll remain truncated unless explicitly renamed. Any thoughts about issues/gotchas we should be aware of in going from a longnames=no system to a longnames=yes one? Many thanks for any input. -- Peter Ivanick Sr. Programmer/Analyst School of Veterinary Medicine, University of Pennsylvania Email: [EMAIL PROTECTED] Phone: 215.573.2306 Fax: 215.573.8777 http://www.vet.upenn.edu/ --- u2-users mailing list [EMAIL PROTECTED] To unsubscribe please visit http://listserver.u2ug.org/
