How to realize universal BASIC7 extension?

[MIRKOSOFT]

Hi!

I look at Mapping C128 to example of extension of BASIC.
But I want to create universal BASIC7 extension where will be not problem to add commands also later, only with their adding to table of commands.
I'm writting about extension only in direct mode.
My problem is still that I don't know how to end routine after executing my own command. If is not recognized, there's no problem, but when recognized is always it beep and jump to MONITOR... (so there's error...)

Thanks for every reply.
