BROTHER
I dont use your basic program , but sometimes I use Micro studio _ basic which is near to it , I am better in ASM, where ASM is the best and the fastest .
so try this program to flash leds fro 1 second and turnoff them for 1second on PORTB of 16F84A , dont forget to connect about 470 ohm with the leds !
START
TRISB = %00000000
MAIN
PORTB= %11111111
PAUSE 1000
PORTB = %0000000
PAUSE 1000
GOTO MAIN
Assembly version of this program
Try to write assembly version yourself

and incase you have problems we can help you .
END
I could not know how to load the HEX file .
