un able to simulate program in keil??

i write a program in c by uvision2 for 80c2051 and it is compiled with no error& no warning and buid hex file
but program can not run properly in keil simulator???

This reminds me:
A production person got hold of a manual for a PDP-8 "symbol?" language manual (a language similar to BASIC) and started playing with ir.

Eventually he managed to make it compile with no errors and came to me and said "there is something wrong with the computer, the program say 'no error' but it does not print what I told it to do, so there must be an error"
