...All I'm trying to do is count from 0 to 255 in binary on the leds so I can learn the chip. It counts properly but doesn't shut off leds while it counts.

By ORing Dig0 with CR, it keeps any bits that were already in the variable.

For CR=0 To 255
    Dig0 = Dig0 | CR
    Low Load
    DelayMS 1
    shiftout Dout,Clk,msbfirst,[Dig0\16]  'no decode
    DelayMS 1
    High Load
    DelayMS 200
Next

Might work better with Dig0 as the FOR variable, and skip the OR.

And it looks like you are using PROTON basic.
They have a PROTON forum here ...

Getting rid of the OR solved it!! Thank you.
I had to do some digging to find out that the pipe was an OR

Thanks again!

Not sure where you did you digging, but the Math Operators section in the Pic Basic manual has all kinds of things to dig in
