Doing some project "commenting" line by line (I could do that, but I wanted people to see that whole community is participating) will attract their attention, and stay with reason "Hey, this is somehow interesting !" and maybe fall in love with electronics .. But hell ye, I suppose years of doing research and engineering pushed us away of principles to help each other ...

I have done this project, with excellent comments, and PM for giving it to you(ment on new begginers) ... And one more thing, this thread will be closed tommorow at 12:00 o' clock and me leaving at 12:01 ...
Wow, a lot of tension here . . . StormRider your statement is a bit confusing, what power do you hold to close this thread ? Except the power to ask the admins to do so?
Anyway that question was rhetorical on my part, it does not answer Your question.
I hope this helps.

Variables are tidy little places in memory to store things, you want to use. In the statement: dta var porta.0 ;KEYBOARD DATA PIN
It assigns PortA.0 the alias dta so you can use the name dta instead of the name PortA.0
The statement following the semicolon is a comment for the programmer so He /She understands what the variable is for.
In this statement: chr var word ; OUTPUT FRAME
It sets an area in memory aside to make 16 bits available accessable by the name " chr ". so if you say chr = 16535 it will set all those bits.
