Responding to: ???'s previous message
I have interfaced keypad with 8051.
that's nice.
i want to store 3 digit number (0-999) . and then display it on three, 7-segment displays.
plain vanilla
can anyone help me how to solve this problem.can i use stack to store digits..?
Yes, but that would give you more trouble than resolution. In C use an array, in Assembler use 3 data slots.
and how can i convert a digit to binary code to send to 7.segment to display that digit.
That depends of the format of the digit (ASCII?) from the keypad
when you say 'binary' what do you mean? binary value? 7-segment bits? ....

you are dancing very close to a -1 rating for "gimme code"

More words do not make you appear stupid, they make you appear clear,

it might be an idea if you posted whet code you have so far.
