and does the code - as posted - look good to you?

I'm a student of Hardware and want to design a calculator with Keypad and Board MCB2300.
In Proteus, work this code without problem.

Can you help me?

That doesn't make sense!

You said at the start of this thread that the code wouldn't even build - so it can't possibly have worked!

regardless there are two possibilities
1) you have downloaded some code that does not work and cry Hilfe - no help for that
2) you have made the beginner mistake of writing the whole shebang instead of gradually writing the code and continuously testing (catch a key, verify - write constant message - verify - ...)
