Abstract


I describe the file format of IDL SAVE files, and a set of accessor routines written in IDL which can read and write SAVE files directly. Data and compiled functions in an IDL session can be stored on a disk file, and restored to a new session at a later point in time. The data are stored using a tag-based format to encourage forward and backward compatibility. Programmers who wish to implement the ability to read, write and interrogate SAVE files, and people who are just interested in ``how it works'' should read this document.
