Sok szenvedés után, eljutottam idáig: Működik (Es sejtem, hogy nem tökéletes ![;]](http://cdn.rios.hu/dl/s/v1.gif)
) 
Ez úton is szeretnek köszönetet mondani a C programozás topik lakóinak

, aztán a munkában kénytelen voltam felfogni. A sok agyi izzadás után meg annyira megkedveltem a Pascalt, hogy otthon is hobbi szinten programoztam. Saját SB meghajtó, hangerőszabályzó, segédprogramok, stb. Már nem programozok, de végülis ha valaki alaposan megtanulja, olyan mint a biciklizés, nemlehet elfelejteni.
