Experts, I'd like to ask how to disassemble DOS executable files (such as .COM and .EXE).
After modifying them, how do you assemble them back again? (Please let me know, thanks) |

For general simple modifications, you can use tools like PCTools.

I already went and downloaded PCTools 90, but I don't know how to use it. Could you explain it?
This is my first time dealing with this kind of tool (though I do have experience writing C language on Unix) |

Using the U command in DEBUG to disassemble works too. Just use the A or E command to modify it and then save it.

Is there a simple example explanation?

For example:
DEBUG A.COM -U ... ... That will do! |
