Regex: 256 characters long
Filename: 256 characters long
32-bit ed.exe

Source Code
===========
src/ed.c
--------
wmake -f Makefile.watcom to compile ed.c into ed.exe
make -f Makefile.dj to compile ed.c into ed32.exe
Run build.bat or build.sh to compile ed.c into ed.com
I made minor changes:
* compile with dev86 bcc, djgpp, or watcom
* add 'n' command
* add '!' command % substitution
* add '!' end of output ! marker
