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

  ERROR - The program contains a syntax error.  BASIC found incorrect or
  multiple operators where another single operator makes more sense, for
  example, 10 A == B.  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.
