 * TW - based on SHL Language File
 * 
 * Spolocne so SHL
 * - kompatibilita s FSHL generatorom 0.4.x
 * - zakladna kostra stavoveho diagramu je spolocna
 *
 * Rozdiely voci SHL
 * - polia maju iny vyznam pretoze spracuva iny stavovy automat
 * - vsetky stavy sa volaju rekurentne
 *
 * function STATE_in()  - vola sa pri vstupe do stavu (Ovplyvnuje flag PF_XIO)
 * function STATE_out() - vola sa pri opusteni stavu (_RET) (Ovplyvnuje flag PF_XIO)
 *                        tiez hned po navrate z rekurzie flag PF_XDONE sposobi zavolanie
 *                        STATE_out() a opustenie aktualneho stavu (simulovany _RET)
 * function STATE_new() - vola sa pri zmene stavu (Ovplyvnuje flag PF_XNEW)
