VMS Help BASIC, /OPTIMIZE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

   The /OPTIMIZE  qualifier  controls  whether  the  compiler  optimizes  the
   program to generate more efficient code for optimum run-time performance.

   The format of the /OPTIMIZE qualifier is as follows:

      /[NO]OPTIMIZE

   The default is /OPTIMIZE.
