- 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.
