PSPP makes use of many files each time it runs. Some of these it reads, some it writes, some it creates. Here is a table listing the most important of these files:
These names (synonyms) refer to the file that contains instructions
that tell PSPP what to do. The syntax file’s name is specified on
the PSPP command line. Syntax files can also be read with
INCLUDE (see INCLUDE).
Data files contain raw data in text or binary format. Data can also
be embedded in a syntax file with BEGIN DATA and END DATA.
One or more output files are created by PSPP each time it is run. The output files receive the tables and charts produced by statistical procedures. The output files may be in any number of formats, depending on how PSPP is configured.
System files are binary files that store a dictionary and a set of
cases. GET and SAVE read and write system files.
Portable files are files in a text-based format that store a dictionary
and a set of cases. IMPORT and EXPORT read and write
portable files.
