Pascal

[Arndt Jonasson]

Actually, there is an editor developed by a computer club here
in Stockholm, which was almost entirely written in Standard Pascal.
The editor (called AMIS (Anti-MISery)) is an (almost) subset of
the original EMACS, and has been quite a success. It was developed
on a DEC10 for the Tops-10 system, but has since then been ported to
VAX/VMS, Pr1mos, NORD-10 among others.
There is no question that AMIS is slower (perhaps even much slower)
than it would have been if implemented in some machinedependent
language, but compared to what editors are otherwise available on 
the named machines, an AMIS, even a slow one, is quite acceptable.
