Help regarding 89c51 port 0 in kiel for lcd interfacing

[Monu Kumar]

I have used port 0 as dataport and port 2 as command port of 89c51uC for 16×2 lcd interfacing and i have simulated my code in kiel during simulation i have observed that port 0 pins are always low in spite of pot0 being high.as shown in scr

eenshot
i would like to know
1)whether there is problem with kiel software & i should use other compilers?
2)will this code when burned in uC will work?
3)should i change my dataport & not at all use Port0?
4) is there a problem in port 0?
