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

  FATAL - A severe error has been detected in the Source  Code  Analyzer
  support  in the BASIC compiler.  If you recompile your program without
  specifying the /ANALYSIS_DATA qualifier, this error should not occur.

  If you receive an error during  compilation  when  this  qualifier  is
  enabled,  please submit a software problem report with the source code
  of a small program that produces this error.
