:=

   Defines a symbolic name for a character string value.

   Format

     symbol-name :=[=] string

     symbol-name[offset,size] :=[=] replacement-string

                                  NOTE

      VSI advises against assigning a symbolic name that is already
      a DCL command name. VSI especially discourages the assignment
      of symbols such as IF, THEN, ELSE, and GOTO, which can
      affect the interpretation of command procedures.
