  INFORMATION - A program compiled  with  the  /ANSI_STANDARD  qualifier
  contains  a  BASIC  feature  that does not conform to the ANSI Minimal
  BASIC Standard.  Although  BASIC  allows  you  to  run  programs  with
  non-ANSI language features, you must remove these features if you want
  your  program  to  be  transportable  to  other  ANSI  Minimal   BASIC
  compilers.
