Hi All.

I have a problem, I want to write a protected-mode program which starts 
another program running in real mode. These two programs should 
communicate through interrupts. My problem is locking the code of the 
protected-mode program. During interrupt handling I want to call some 
functions which is written by somebody else ( GRX20 ) and I don't know 
which other procedures it calls. I think I should lock the whole code ( 
and only the code ) because it solves that I don't know the amount of 
area to lock. So my question is. How can I lock the whole code?

thanks
Rebecca

p.s.: I'm sorry for my bad english.
