Which routines calls BASIC after pressing Return?

[MIRKOSOFT]

Hi!

My problem is that I want to make an extension of BASIC V7 only in direct mode.
There's no problem to relocate vector $0302, but when is my command recognized and executed, it jumps to else other routine(s) before print prompt READY.
I need to know which vectors I need else to relocate or which routines calls BASIC ater ($0302)...

Thanks for every reply.
