spss +m at your UNIX prompt.
SPSS will load in its full-
screen interactive processor called Manager (the Input, or
editor, and Output Windows), and will put your cursor in the
Editor (the bottom screen) in Edit mode. Here, you may enter the
Menu System (ESC-m) and build your programs from the menus,
remain in Edit mode and type your programs yourself, or bring in
programs stored in external UNIX files. The available online
help is described below.
There are many "switches" you can use to do various things with your SPSS session, and these are documented in "man spss" and in the User's Guides (see "Help Documentation" below), but one deserves mention here. SPSS sets up its session with a default amount of working memory (512K bytes) but this can be raised by the user if necessary. (Usually this becomes necessary when you see a message during a session that a command or procedure needs more memory.) This is done with the "-s" switch (-s for "space"), followed by a designation in bytes or Megabytes of the amount of memory desired. Example:
spss -s 7m
requests that an SPSS session begin with 7 Megabytes of working memory.
To invoke the SPSS Batch Facility (Version 11.x), first source the setup file:
source /usr/usc/spss/11.5.1/setup.csh
Then use the spssb command followed by the name of your
syntax file:
spssb myprogram.sps
