Vaclav,
Thank you for answering. You wrote what I wanted to read...
As my code will be very large, I'm thinking on change the platform (AVR) and
use another free C compiler (avr-gcc). I'm still testing this free compiler
to see how it optimizes the code's size.
I like SDCC, but I believe that the optimization of the code's size is
something very important.
