A.4.2 Predefined environment variables
There are two environment variables predefined for use in environment
- Defined as the version number of PSPP, as a string, in a format
something like ‘0.9.4’.
- Defined as the host architecture of PSPP, as a string, in standard
cpu-manufacturer-OS format. For instance, Debian GNU/Linux 1.1 on an
Intel machine defines this as ‘i586-unknown-linux’. This is
somewhat dependent on the system used to compile PSPP.
Nothing prevents these values from being overridden, although it's a
good idea not to do so.
