VMS Help DTM, COPY, TEST_DESCRIPTION, Command Qualifiers, /PROLOGUE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

   /PROLOGUE=file-specification
   /NOPROLOGUE

   Determines whether a test prologue file is associated with the
   test description. The prologue file associated with the existing
   test description is also associated with the new test description.

   The /PROLOGUE qualifier causes the specified prologue file to
   replace the existing prologue file. The /NOPROLOGUE qualifier
   specifies that no prologue file be associated with the new test
   description.
