Hello sir..need help to finish my program about Timers using MicroC..in PIC16F877A..

unsigned short kp;
unsigned short cnt;

       do
       kp= Keypad_Released();  //store key code in variable
       while (!kp);     //prepare value for output,transform key to it's ASCII value
       switch(kp)
       {
        case 1: kp=49;break; //1
