Hi

I have an array bug. Sometimes it crash the application when exit (on win8), sometimes I have an error message at line 38, sometimes nothing happens.

I think it could be great to have ALWAYS an error or a message with that kind of error.
Should it be fixed in the v2 ?

Type sType

    Name$ 
    x as integer
    y as integer
  
Endtype
global dim test[0] as sType

global Param as integer

Init()

do
    Event()
    Sync()

loop

// on win8, crash when exit

function Init() '{

    dim test[10]
    for i =0 to 10
        test[i].x = i
        test[i].y = i 
        test[i].name$ = str(i)
    next i

EndFunction '}

Function Change() '{

    For i = 0 to 50
        // should crash or give an error at i = 11
        // because test[] has only 10 elements
        test[i].x = 10
    next i


EndFunction '}

Function Event() '{

    if param < 200
        Param = param +1
    elseif param < 210
        param = 211
        change()
    endif

EndFunction '}

This one is well known. I hope Paul has fixed this in next alpha since it's a compiler bug. It's the number one likely suspect of random crashes.

It would be a good idea to add some Pascal syntax to the compiler:

for x := Low(test) to High(test) do ....

Saves a lot of dangerous literals.

-- Jim - When is there going to be a release?

Yes, already implemented and will come in the next alpha.

Shouldn't this:

dim test[10]

Be this:

dim test[10] as sType
