simulation stopping

[lake]

hi when i test my programming whichthere is nothing wrong with after about 30seconds the simulation stops as ive said my programming is fine because it runs throught it a few times before stopping is this anything to do with the gosubs thingy in the simulation ??? help please

Hmmm,
Looks like your code you attached to your message didn't work!

Cheers,

yes srry i havnt yet done the symbols but this shouldnt be a problem as it is code error or something that i dont knwo about yes like i said it runs for bout 30-40 secs then stops on one of the if...then....gosub... in the PONG: heading it always seems to stop here any help will be great thanks.
its a game where you have two paddles and a ball which you batt around wen you miss the other person gets a point first to three wins its played on a 8x8 dot matrix but only 7x8 is used for the game the top row is for the points that you get


main:
let b10=0
let b11=0
goto startvalues
startvalues:
let b6=28
let b7=28
let b8=-1
let b0=4
let b1=3
let b2=1
goto pong
pong:
do
let b9=b9+1
gosub inputbuttons
gosub positiondata
gosub outputs
loop until b9=2
goto ball2
inputbuttons:
let dirsc = %00000000
if pin0=1 then gosub up2
if pin1=1 then gosub dw2
if pin2=1 then gosub up
if pin3=1 then gosub dw
return
positiondata:
if b1=7 then gosub negb4
if b1=b8 then gosub posb4
if b0=7 then checkrightpad
if b0=0 then checkleftpad
return
outputs:

never mind me it my programming opps yes looking in to the gos command you can only have them 4 times (deep) so.

main:
gosub one
one:
gosub two
two:
gosub three
three:
gosub four
four:
gosub one

and whn it gets to FOUR: it will stop
as it has reached it limit diffent picaxe have different limits stupid me lol now i just have to find where it is over four deep which will be hard

I think you're on to the case already.

Have a look at "GoSub" in the commands manual. Due to the limited RAM available in PICAXE chips, the interpreter limits the depth of subroutines to 4 (8 on the x1 and x2). Page 46 of the command manual.
