L1 PIN 1
L2 PIN 3
L3 PIN 5
L4 PIN 7
L5 PIN 9
L6 PIN 11
L7 PIN 13
L8 PIN 15

ax VAR Byte

DELAY CON 50
Main:
DO
PAUSE Delay
ax = ax + 1
GOSUB Bar_Graph
LOOP


Bar_Graph:
L1 = ax.BIT0
L2 = ax.BIT1
L3 = ax.BIT2
L4 = ax.BIT3
L5 = ax.BIT4
L6 = ax.BIT5
L7 = ax.BIT6
L8 = ax.BIT7
RETURN

You need to make your pins outputs (TOGGLE does that "under the hood"). You can do it with one line of code:

DIRS = %1010101010101010

A "1" makes the pin an output, "0" an input. Put this line of code before Main.
