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

  WARNING - A program containing multiple  compilation  units  has  been
  stopped  while running in the environment due to a STOP statement or a
  CTRL/C entered by the user.  The  NOFRAME  error  indicates  that  the
  routine executing when the program stopped is not the last compilation
  unit in the source file.  You can examine  or  modify  a  variable  in
  immediate  mode  only  if  the current routine is the last compilation
  unit in the source file.

  If you do not intend to debug  your  program  in  immediate  mode,  no
  action  is  required.   If  you  do  intend  to  debug your program in
  immediate mode, make the routine that  you  want  to  debug  the  last
  compilation  unit  in  the  source  file.   The  symbols  for the last
  compilation unit are always available.  Alternatively, use the OpenVMS
  symbolic Debugger to debug your program.
