Virtual System
Tables Guide
Written by Dan Foreman,
Current Edition: July 2008
Virtual System Tables (VST's) were added
in V8.2. VST's provide access to data
that was previously only accessible
through the promon utility. The Progress
documentation gives a basic description
of each Virtual System Table (VST) but
is generally inadequate for anyone attempting
to do so serious work with VST's.
