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

   /VARIABLE=(variable-name[=variable-value],...)

   Enables you to associate existing variables with the test
   description you are modifying. The variables you specify must
   be defined in the Digital Test Manager library by using the CREATE
   VARIABLE command. A variable associated with a test description
   by this qualifier is local in scope.

   The /VARIABLE qualifier also enables you to redefine values for
   the variables you specify. If you specify an optional value, the
   variable takes on that value only for this test description; the
   value of the original variable is unaffected.

   If you specify more than one variable name, separate the names
   with commas and enclose the list in parentheses. If you specify
   only one variable name, omit the parentheses. You cannot use
   wildcards.

   The /NOVARIABLE qualifier disassociates the specified variables
   from the test description.
