The UNIX editor ed is running under MPE on the HP3000 - written in Fortran.

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. Larry Dwyer ucbvax!hpda!ld
