vt100 non-support
At our site, we have two VAX 11/780s; one runs VAX/VMS, the other runs 
VM/UNIX.  Since the most commonly used editor on VMS, EDT, requires a VT-100,
we have a number of VT-100 terminals.  Unfortunately, termcap and the 
applications which use it do not seem to support VT-100s very well.  In
particular:

1)  Worms does not call termcap properly to get the time delays expanded.
    Thus, a series of 5's and 2's remains on the screen.
2)  The al and dl capabilities in the vt100 termcap entry contain %2's.
    In order to delete or insert a line on the VT-100, it is necessary to
    change the scroll region and scroll as appropriate.  To change the
    scrolling region, a line number is required.  However, there is nothing
    in the termcap documentation that implies that the al and dl capabilities
    accept a line number as a parameter.  As a result, none of the programs
    using these capabilities work on the VT-100.  In particular, vi is
    unusable.
3)  The cs capability is not implemented in any program that I can locate.
    If it were implemented, this would eliminate the need to fix problem
    number 2 above.

Has anyone else encountered similar problems with the VT-100?  Does anyone
have any solutions?
