stepper motor programming.....help me

hi...
can anybody check my programming...my programming cannot be run...
i dont know what is the error....please check and inform me a.s.a.p..

i suggest, copy my programming and run it in c programming..so u will see clearly my programming...please help me..

kindly help...

p/s : i want to control stepper motor through parallel port

violation of ANSI: there's no conio.h. AFAIK, this exists only on windoze/dos machines.
as for the program: eh, outportb() macro expands to nothing.
