Thank you for your attention. Now my program is working fine, I can access external devices, read keyboard and switches, write to lcd etc. :o)))
Andy: you are right, but in this special case Keil and Raisonance works the same way. Isn't it? I want Keil C programming example, because a lot of people are knowing (and using) Keil C. I don't know the statistics, but at this forum a lot of people have been asking about Keil C.

Greetings,
Jacek
