Simple Counting Program

b1 var byte           'declares the variable b1 as type byte
poke TRISB, 0          'defines the all pins on the portB as output pins
let b1=0
loop:          'its an identifier for iteration
pause 1000          'it pauses the programm execution for 1 second
poke portB,b1          'writes the value of b1 on portB(decimal<=>binary)
b1=b1+1          'updetes the variable value to the nxt value
goto loop          'substitution for the loop statement,a simple goto
