#185876 - typical beginner issues
Responding to: ???'s previous message
mov p1,#11111111b ;port 1 makes input port 
clr p1.0 ; port 1 zero bit clear 
etc ....

1) there is NO SUCH THING as an input port on the '51 http://www.8052.com/faqs/120176 http://www.8052.com/faqs/121619
2) comments are to describe the intention of the code, not "explain the assembler"
3) not using pre and /pre
