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

  ERROR - The program contains a syntax error.   BASIC  assumes  that  a
  keyword  has  been misspelled, and compilation continues so that other
  errors may be detected.  The actual program line remains unchanged and
  no  object  file  is produced.  Examine the line carefully to discover
  the error.  Change the program line to correct the syntax error.
