Library /sys$common/syshlp/basichelp.hlb Help  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The HELP command displays on-line information about VAX BASIC  statements,
  commands, directives, functions, conventions, and other topics.  Type HELP
  to see a list of topics.  Then enter a subtopic for more information.   If
  you  type  a  question  mark  in response to the prompt for a topic, BASIC
  displays the list of available topics.
