Scott Networked Computer Systems Group Computer Science and Applications Section Jet Propulsion Laboratory California Institute of Technology 1. FREE .COM file to display the amount of free space on a mounted disk volume. From the Radio Astronomy/VLBI hackers. Gee I wish you could pass more than eight parameters to a .COM file! 2. INUSE An INUSE is some sort of display to leave on your terminal when you leave, but not for long enough to justify logging out. INUSE.COM produces the "Caltech Standard In Use" display on a VT100+AVO or equivalent. KZLINUSE.COM was written by a Caltech student whose name has since been forgotten... it's a little unusual in that it cycles through six frames. Works on any 24x80 CRT; best viewed from a distance. "Everyone writes an INUSE; it's easy to do and makes you feel important." Apologies to Rob Pike (now at AT&T Bell Laboratories). 3. MAILCHECK If I had to pick one "most useful .COM file" this would have to be it. Given a list of usernames (default is your own) it displays how many unread MAIL messages there are for each. Requires read access to SYS$SYSTEM:SYSUAF.DAT. 4. RMS Cheat Sheets These have literally saved hours of my time. A must for the true RMS hacker. 5. SCRFT I promised this at the last (Las Vegas) Symposium. Intended for publication in Pageswapper. Read the .DOC file. 6. USERS VMS version of the program of the same name written by yours truly a few years back for the DECsystem-20, and incorporating some improvements suggested by Ian Macky (now with the Network Information Center at SRI International). Read the .DOC file.
