Yes, this is possible as long as you make sure you write code and data
to the correct spaces in the file. If you are going to change any code
in an already compiled file, I would suggest you use Borland's Turbo Debugger
to find out where the code should be inserted, and write down the hex
codes for the code you want to insert. Then you can use any disk editor to
change the code you want to modify.
