DOS Debug Question

Ok just for the fact that i dont know i am asking this somewhat weird question.


With the DOS Debug mode..can i take any windows program and actually modify it someway?


Thanks

Yup. You just have to know what you're doing!

But how may people actually know how to use MSDOS Debug?

how do you enter the dos debug thing?

I would be surprised to discover that Debug is included in the DOS available with Windows 9x. Perhaps it is.

To start it, you type "Debug" from DOS Command Prompt (No quotes, of course). It might be better to try to run Debug from Start, Run. If Windows 9x allows Debug, it might be smart enough to set up a special environment for it.

You might have to Boot from a DOS 6.22 (or 5.0) Diskette. First, you might have to copy all the DOS Files into a Directory somewhere. I do not think that DOS 6.22 can read FAT32 files, so you might not be able to do anything with DOS Debug.

You could use Ztree or some other Utility which can run under Windows 9x and edit disk Files in Dump Mode. Ztree dump mode shows ASCII & Hex values, allowing you edit in either format.

BTW, Ztree is a very handy File Management utility. It does not replace Explorer, but is more convenient for many purposes. If any of you remember Xtree for DOS, Ztree is the Windows 9x version.

Windows 9x comes with its own debug. To edit a file you just type "debug [filename]". To view in hex press "d". To view in assembler, press "u". Just remember the bytes are stored as high order /low order so you'll have to reverse them to make any sense out of it
