hardware counting while software runs

And depending wich PIC you're using you may have 1,2,3,... Timer/Counter who can work with external Clock. Be sure the PIC you select provide you at least 2 of these with external Clock Source.

Or there's still this interrupt on something stuff.

You know what i want to say now

Yeap, I forgot to say that the code above is for 16F877-20Mhz.

I know what you mean Steve! I will never forget.

Thanks,
I will take this code home and chew on it a while . . . . I am not manipulating data in an lcd, rather I am using it to control hardware.something like so:

x var byte

main:
if porta.0 !=0 then
pause50
DoSomthing
else
endif
goto main


DoSomething:
for x = 50 to 0 step - 1
goto encoder
portB.5 low
next x
return

encoder:
Portb.5 high ' to power up encoder
some code here to count encoder subtracting code from var X
return

.....


main:
if porta.0 !=0 then
pause50
DoSomthing 'is a goto not a gosub
else
endif
goto main


DoSomething:
for x = 50 to 0 step - 1
goto encoder 'another one here
portB.5 low
next x
return

encoder:
Portb.5 high ' to power up encoder
some code here to count encoder subtracting code from var X
return

I guess this was a quick example.
Check "goto" !
