Is it possible to add codes to methods at runtime?


Yes.

Like you can define new Classes at runtime, you can update a class at runtime.

- CLEAR CLASSLIB from memory
- Open the VCX table with exclusive
- option: set tablebuffer
- locate the Class
- clear the objCode
- Change the Methods script
- option : tableupdate
- pack memo
- close the table
- COMPILE the vcx like a classlib

same process with a PRG class

A critical point is #INCLUDE .
