menu selection

[NURULHAIZA]

guys i have tried everything that you told me...but it still the same....once the rx received data from tx and display it on LCD it will stop there and will not execute the other loop. do i need to change anything at tx?

Let's try to debug this...
Your code is running to here?

TEMP:
'SNIP
    LCDOUT $FE,$C0,dta(0),DTA(1),DTA(2),DTA(3),DTA(4),DTA(5),DTA(6),DTA(7),DTA(8),dta(9),dta(10),dta(11),dta(12),DTA(13),DTA(14),DTA(15)
    RETURN

Then ends up here

main: 
'ADD LED TO FLASH TO SEE IF IT IS HERE OR DISPLAY "AT MAIN" TO THE LCD 
    if portB.1=1 then                               'arrow down
        push = push+1 : goto selection : endif
    if portA.1=1 then                               'arrow up
        push = push-1 : goto selection : endif
    pause 5000
    goto main

Then when you get here

selection:
"DISPLAY THE VALUE OF "push" TO THE LCD
    pause 200
    if push=1 then screen1
    if push=2 then screen2
    if push=3 then screen3
    if push=4 then screen4
    if push=5 then screen5
    if push=6 then screen6
    if push=7 then screen7
    if push=8 then screen8
    if push=9 then
        push = 1 : goto screen1 : endif  
    if push=0 then
        push = 8 : goto screen8 : endif
    goto main

I have a sneaky suspicion you will need to use >= in place of =
Does that make sense?

Sorry to say but I have tested the menu selection on a simulator and if you change the pause to 50 it works fine (although I would have used a LOOKUP with BRANCHL), but leaving that aside, I suspect you have been naughty with your syntax - you define a word and then treat it like an array. A simple little test of:
dta = 513
dta1 = 514
extra1 = 515
extra2 =516

LCDOUT dec dta(0), " ", dec dta(1), " ", dec DTA(2), " ", dec dta(3), " "

gives this result:
513 514 515 516
indicating that
dta(0) = dta
dta(1) = the next defined variable etc
quite unpredicable results - you must define an array and reference it with "square brackets" or better still with the STR expression. Eg:

Buffer var byte[16]
HSERIN 1000, tsync, [str Buffer\5]
