    Default 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
