The same "ed" which is running on HP3000's under MPE runs on HP1000's in
RTE-IV and RTE-VI.  Both editors share the same source file.  It was
based upon the Software Tools ed, but written in fortran (about 13000
lines) with some machine dependent assembly to speed it up.  The
assembly code is reasonably modular.  In addition to extended pattern 
matching, it sports most of the "open mode" commands available in "ex".
This version was written by Ellis Cohen at UC Berkeley (he is no longer
there) while he had access to both HP OS's and UNIX on a VAX.
