The main documentation file is vltdocs.arc, a separate archive in BIX 'listings', for VLT version 3.656. However, it is a TeX source file. For a printed copy, send a note by US mail to Willy Langeveld, SLAC bin 97, P.O. Box 4349, Stanford 94309. Other than that you'll just have to play around and ask questions in amiga.user/main on BIX... Previous releases included RexxArpLib.library and RexxMathLib.library. These are now distributed in a separate archive. There is a short doc file for the PingServer (the Ping program), and other files with documentation on changes to VLT since version 3.656. Willy.
