warning: [W180] Unreachable code problem?

[RandomiserUsr]

Hi  if i compile this, says

warning: [W180] Unreachable code

but i don't know why

the version is  zxbasic-1.15.2

Code:

' EXAMPE UNRECHABLE CODE

declare sub mySub()

Dim myNumber As uByte
cls

myBucle:
    for myNumber = 0 to 7          
        mySub()                  
    next myNumber
    goto myBucle

sub mySub()

end sub

Looks like there is escape from the loop? 
and an empty mySub() ?

Thanks

if i fill the sub like this




sub mySub()




   dim a as ubyte


   dim b as ubyte



   a = 1


   b = 1


   a = a + b




end sub




the problem is the same I writed an empty sub only as a example I found the problem in first time with not empty sub



and where is the escape from the loop?  i don't see it

is a very very little structure.  Just one goto, one for and one sub

Hi, sorry I missed off some of the message.

I can't see how this myBuckle loop would exit?

myBucle:
for myNumber = 0 to 7
mySub()
next myNumber
goto myBucle

Lastly what is the full code listing and full error you are getting?
