The Log File is a post-mortem listing of all commands issued and successfully executed during a working session. It is kept on leaving SIC (by using EXIT). Some commands like HELP are not put into the Log File. Most programs using SIC put the Log File in the GAG_LOG: area (usually your default directory, but see ``Customizing'') to avoid multiplication of files in a directory tree, and purge it upon exit keeping the last two or three versions. Log Files can be used as the basis of subsequent procedures. If you are short of disk space, purge and delete yourself the log files.
