For most purposes, cases should be limited only by the amount of
disk space you have available, with a hard limit of about 2
billion cases.  Increased RAM will speed up operations, if you
allow PSPP to use that RAM with SET WORKSPACE.

Variables are limited by your machine's memory, again with a hard
limit of about 2 billion variables.  Each variable should require
less than 1 kB of RAM, although large numbers of value labels
increase memory requirements.

Large numbers of cases and variables have not been thoroughly
tested.

I should add these figures to the documentation.
