Odd; I could've sworn that "URK" was un-rotated i.e. traditional format; are you sure about that? And "unswbatch"... Ahhh... I must take a look at that distribution some time, to see whether it has my fingerprints on it; Kevin Hill and I totally rewrote the system, throwing out IanJ's rubbish, with him doing the application stuff ("submit" etc[*]) and me doing the driver. After that, it actually worked (once I'd figured out a nasty bug in KRONOS' UT-200 driver, that led to a POLL/REJECT loop). [*] I did a memorable hack to "submit" once; you see, we had an old VT-05 in the fishbowl, facing outwards for the sheeple, and it displayed the batch queue (by title) in real time. Well, me being me, I hacked up the aforesaid "submit" command to take multiple arbitrary files as input with a specified title, so for a while it displayed "xxx... LLAMAS ARE BIGGER THAN FROGS" (job names were 8 characters, and I have no idea how that will display in people's MUAs).. (I *think* I was actually working for them at that time.) -- Dave Horsfall DTM (VK2KFU) "Those who don't understand security will suffer."
