 Technically, that only disables one command/address scheme.
 The command was OR, which I didn't need, and luckily I never needed
 to reference any address ending in decimal 9.
 That is no big deal. All I needed to do was open a file which I 
 redirected stdout to and let Command.com handle opening it for
 me, but make sure to use >> and not >. ;-)
 Set the file pointer to the correct address which I retrieved using
 DOSSHELL and 9 and write * followed by two spaces. Later I changed it
 to *3* follwoed by two NUL's using debug though. I also learned shortly
 after that QBASIC can be used to edit file in binary mode and it can
 set a file pointer.

 No, no, no. QBASIC.EXE houses EDIT as well as DOS's HELP program.
 that's why ypu patch the QBASIC.EXE file and not EDIT.COM whish IMHO,
 is an utter waste of time to keep as a batch file containing

 @ECHO OFF
 QBASIC /ED %1

 Takes up less space than edit.com actually does. Just name it EDIT.BAT
 and you should hve very little probelms, unless someone hardcoded
 EDIT.COM in theior program for an exec.

 Because I had misplaced it in my Windows directory and I really hate
 going through a week of backup's for one little file, I figured I'd 
 eventually get around to it the next time I backed up, but I found it 
 before then. trust me, I didn't enjoy using EDIT for this purpose.
