VMS Help BASIC, /WARNINGS  *Conan The Librarian (sorry for the slow response - running on an old VAX)

   The /WARNINGS qualifier lets you specify  whether  the  compiler  displays
   informational or warning messages.

   The format of the /WARNINGS qualifier is as follows:

      /[NO]WARNINGS[=({[NO]WARNINGS      },...)]
                      {[NO]INFORMATIONALS}
                      {ALL               }
                      {NONE              }

   Specifying /WARNINGS=NOWARNINGS causes the compiler  to  suppress  warning
   messages.   Specifying  /WARNINGS=NOINFORMATIONALS  causes the compiler to
   suppress informational messages.

   The  /NOWARNINGS  qualifier  causes   the   compiler   to   suppress   any
   informational or warning messages.

   /WARNINGS = ALL is the same  as  /WARNINGS  =  (INFORMATIONAL,  WARNINGS).
   /WARNINGS = NONE is the same as /NOWARNINGS.

   The default is /WARNINGS = (INFORMATIONAL, WARNINGS).
