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

  INFORMATION   -   This   error   is    reported    only    when    the
  /FLAG=BP2COMPATIBILITY qualifier is in effect.  The program contains a
  language element that is not supported in  BASIC-PLUS-2,  for  example
  RECORD  statements.   If  the  program  must  run under both BASIC and
  PDP-11  BASIC-PLUS-2,  you  must  remove  the  incompatible   language
  feature.
