INFORM/V User's Guide

Appendix B  FILES USED BY INFORM/V 

INFORM/V often creates and uses files that are not apparent to the user.
For the most part, you need not concern yourself with these files or the
formal file designators that INFORM/V uses.  Information about the files
that INFORM/V uses is collected here for those advanced users who need to
change the default file environment.
