I posted this from another address before, but it's not showing up in the archives. I apologize if this is a repeat. I've just finished a module to get and set logical names, using hooks into sys$crelnm and sys$dellnm. (I was planning to write a hook into sys$trnlnm to but haven't gotten there yet. If anyone else wants to do that part, that'd be fine.) You can find it at http://vmsbox.cjb.net/~forrest/. I suspect many of you will find it useful. Have fun! Forrest
