More specific OS version reference is term Jaguar (10.2.x) or Panther (10.3.x); lower order digit group represents the patch level. A more correct term for the GUI tends to be Cocoa or Aqua. That might be the programming interface to it; I don't write Mac GUI applications. >> Unix is when you have 3 letter commands and 1400-line >> unaudited manpages written by engineers (as opposed to technical >> writers), and the command line completion does not work, >From a terminal window, I have all those 2 & 3 & 4 letter commands. And my command name and file name completion certainly DOES work; I have to hit escape twice on Mac OS 10.2 (as opposed to once on some other Unix shells). And it is trivial to port Unix utilities to or from Mac OS X -- I write & test tools via OS X command line then the exact same source compiles on Solaris, HP-UX, & others. >> thing you can click is the ball point pen on the desk.

Exactly. I spend 2/3 to 3/4 of my time in a terminal window. > It's a Unix box with a pretty (and very useful) GUI. They've just > hidden that fact well enough the average doofus doesn't realize it. And it has sufficient market penetration that you can get the GUI tools that you need, like Photoshop, Acrobat Reader, etc. Lee Jones -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
