trying to do a scroll window

Code:

---

clear
define osc4
cmcon0=7
ansel=0
led var byte
ledstates var byte
trisstate var byte
delay var word
noghost var byte
noghost= %111111
delay= 1500
porta = %110111
main:
for led = 0 to 3
select case led
case 0 : ledstates =%000 : trisstate =%111
case 1 : ledstates =%010 : trisstate =%100
case 2 : ledstates =%001 : trisstate =%100
case 3 : ledstates =%100 : trisstate =%001
end select
trisio = noghost
gpio = ( gpio & %111000) | ledstates
trisio = (trisio & %111000) | trisstate
pause delay
next led
trisio = noghost
for led = 0 to 2
select case led
case 0 : ledstates =%010 : trisstate =%001
case 1 : ledstates =%100 : trisstate =%010
case 2 : ledstates =%001 : trisstate =%010
end select
trisio = noghost
gpio = ( gpio & %111000) | ledstates
trisio = (trisio & %111000) | trisstate
pause delay
next led
trisio = noghost
goto main
end
this
could
be a
a
useful
tool
but
I wonder
how
long the
 
list can be
 
and still
be
visible
