PIC 16F877A Keypad interfaceded with Input and LCD as Displays Output

[np123]

I am new to PIC programming,, have been fiddling with BLINK.Bas
and managed to make the LCD show a message "LED Blinking"
just before the LED blinks.

I am using the MCS PICBasic Pro for the sake of compiling and am using the
DIY K149 Pic Micro Programmer to program my PIC16F877A.

Now I was wondering how would I be able to use the Keypad as an input
and display things on the LCD.

I am sure my question is very newbie, but if someone could explain me
how I could manage my inputs and storing into registers and then output
it to whatever port pin etc., then it would be of great help.

Thank you!
