What happened to array sizing?!?

New comment
 

Guys, there are strange things in MT4 with array sizing that never happened before.

If I use this, no problem:

double array[65529];

But if I use this, I got a compiler message ("the size of local variables is too large (more than 512kb)")

double array[65530];

I can't remember such limitations in the past.

Also, earlier I could define a function like this:

#define SIZE1  10

#define SIZE2  20

int SomeFunction(int array[SIZE1][SIZE2]){...}

But now, it doesn't work, SIZE1 is ignored.

Can you confirm my observations?

The second question, it doesn't make sense to define a size for first dimension of array in function definition.

Why?! It is a static array. I always did it and worked well.
 
For first question, there has been such limitation as documented here: https://docs.mql4.com/constants/errorswarnings/warningscompile

Try an array of dynamic size and resize it as needed.

Because array is defined in the body, not in the function definition.

I think it is a false statement. Where do you see such rule?

As I said, this worked well until now. But now it stopped working.

Regarding the first problem: is there any array-size limitation?

Arrays are passed to functions by reference.
I tried to help.
If it worked before, it doesn't mean it was correct.

Yes, the system resources, if the memory is full, or it can not be allocated, the ArrayResize function won't succeed.
 
There's always a limit on index size:

Total amount of elements in the array cannot exceed 2147483647.

Yes, I forgot to write the &:

int SomeFunction(int &array[SIZE1][SIZE2]){...}

Array sizing: this code below gives 0.

double array[][5000];
ArrayResize(array,5000);
Print(ArraySize(array));

You should check the return value of ArrayResize, if it is false, then check for error using GetLastError.
