I wanted to use small plug-ins, but now I think I should use DXE instead.
Can someone send me a little example of DXE program, C++ program using DXE,
and
instruction how to compile/build it under RHIDE ?
 __PLEASE__ can You write few lines of example, not just tell me to read
DOCs...
What are restrictions of DXE program ?

I cann't beacause this part of Allegro is written in assembler and it is
very hard for me to use it in my program.
Allegro doesn't exacly call copy of function code stored in memory, but it
calls it's own, real-time-compiled code, that is written in assembler.
But it doesn't real matters, I will use DXE...
