DCLTABLES has EDIT /TECO and it points to
SYS$SYSTEM:TECO32_TV.EXE that does not exist.

I believe the _TV suffix indicates that it is
a translated VAX image.

VSI has states that they will *not* provide an
IEST utility (similar to VEST and AEST).

Yes - it very much look like a left over in DCLTABLES.

And if TECO on Alpha indeed was VEST'ed (and AEST'ed to Itanium????)
then it seems rather unlikely that it will ever show up on
x86-64.
