     D.E.C. VT-100 keys are not redefinable.  Each key sends a fixed escape
code.  Thus, the [ GOLD / PF1 ] key can not be exchanged with the [ PF4 ]
key.  Their hardware actions are fixed.  The keys can only be reassigned
via changing the --SOFTWARE-- routine executed for any particular keypress.
VAX/VMS DCL allows you to map and remap the VT100 keys at the OS level.
You can redefine VT-100 keys under program control, but you can do that for
--ANY-- key on your keyboard (e.g. if 'a' is pressed go West, etc....).
D.E.C. VT-100 ANSI is not much like MS-DOS ANSI.SYS in several respects.
PF1, for example, will send an <ESCAPE><Capital-O><Capital-P> in D.E.C.
VT-100 ANSI.  There is no way to change this sequence short of turning on
VT-52 emulation and turning the VT-100 into a VT-52 (which changes the
screen mapping and everything else about the terminal).  Perhaps if we had
even the vaguest idea of what it is you are trying to accomplish, we could
offer some meaningful advice.
 
     Here is the VT100 ANSI function keypad as I know it:
     [ <ESC> O P ]  [ <ESC> O Q ]  [ <ESC> O R ]  [ <ESC> O S ]
     [ <ESC> O w ]  [ <ESC> O x ]  [ <ESC> O y ]  [ <ESC> O m ]
     [ <ESC> O t ]  [ <ESC> O u ]  [ <ESC> O v ]  [ <ESC> O l ]
     [ <ESC> O q ]  [ <ESC} O r ]  [ <ESC> O s ]
     [      <ESC> O p           ]  [ <ESC> O n ]  [ <ESC> O M ]

     
     The function keypad is turned on with:
          <ESCAPE> =
     The function keypad is turned off with:
          <ESCAPE> >
 
Best of luck!
