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

  Tells BASIC to make calls to the Run-Time Library that set up the  stack
  for  BASIC  variables,  set  up  dynamic  string  and array descriptors,
  initialize variables, and enable BASIC error handling.  Use NOSETUP  for
  short  BASIC  subprograms  that use only numeric and fixed-length string
  operations.  NOSETUP should be used ONLY  on  routines  that  have  been
  thoroughly  debugged  and whose execution time is critical.  Using BASIC
  I/O facilities in a routine compiled /NOSETUP is NOT SUPPORTED.
