16LF1824 strange problem

[EarlyBird2]

I tried your code...the same. But is something what I don't understand ... I used 2 different variables and work great . It don't work if I use the same variable ! Today I'll try initialisation from Alain's code. In this moment my code work good, but I want to understand whats happen inside.

varb var byte
vara var byte
varb = 0
vara = 0
 pause 200

init:
 pulsin portc.2 , 1, vara
 if vara < 140 or vara > 160 then init
 pause 100
 pulsin portc.2 , 1, vara
 if vara < 140 or vara > 160 then init
 if vara > 140 and vara < 160 then goto beep
 goto init

beep:
pulsin portc.2 , 1, varb
....code....
goto beep

1000 x THX

Are you saying the init routine works but beep does not work if vara is used but does work if varb is used?
If so I am puzzled.
Can you post the code in beep?

Its very strange! If I use the same variable in init and in main(another loop), no work properly. If I use different variables, work great. Totally mistake!

Code:

varb var byte
vara var byte
x var byte
divf var byte
divf = 0
varb = 0
vara = 0
x = 0
pause 200

init:
pulsin portc.2 , 1, vara
if vara < 140 or vara > 160 then init
pause 100
pulsin portc.2 , 1, vara
if vara < 140 or vara > 160 then init
if vara > 140 and vara < 160 then goto beep
goto init

beep:
hpwm 1 , 10, 3000
high front
pause 80
low front
pause 200
hpwm 1 , 5, 1200
high front
pause 80
low front
pause 200
hpwm 1 , 10, 3000
high front
pause 80
low front

main:
pulsin portc.2 , 1, varb

hpwm 1 , x, 1954

'========================miss signal===========================
if varb < 50 then
varb = 150
x=0
low front
endif
'================================================= =============

if varb> 160 then
high front
divf=255*(varb-160)/30
if varb > 190 then varb = 190
if x > 255 then x = 255
if divf > x then x=x+2
if divf < x then x=x-6
if x < 15 then x=15
endif

if varb < 160 and varb > 140 then
low front
x = 0
endif
goto main
end
