Andrei Trukhanovich:

it seems that count=0 works in the same way as count=-1 and in case of "" it copies a terminal null.

This is where the error lies, just shown with a practical example where ingeneral there can be both empty strings and count = 0 by itself (in a loop for example)

A100:

And how many

should it copy if count = 0 ?

Hint: 3 characters are copied when count = 3.

I'm not even going to argue. It works correctly.

Andrei Trukhanovich:

Looks like count=0 works the same way as count=-1 and in the case of "" it copies a terminal null, so you can't properly convert an empty string without additional checks

An empty string (NULL) does not contain a terminal null. Everything seems to work logically there.

If there are no arguments, then of course you don't have to.

An empty string is "" and NULL is not an empty string - it is an uninitialized string, i.e. it is not a string at all andStringToCharArray with NULL does not work, error result: 4009

You are mistaken, to put it mildly.

Please explain if you have anything to say on the merits

string Str = NULL;

Print(Str == "");

Result: false

What is the contradiction with this statement?

Empty string is "" while NULL is not an empty string - it is an uninitialized string which means it is not a string at all andStringToCharArray with NULL does not work and causes error: 4009

And what is the contradiction with this statement?

The variable is initialized. You can, of course, think of string as a pointer to an internal string class.

If it's initialized, then why the

void OnStart()
{
    uchar array[];
    const string text = NULL;
    StringToCharArray( text, array );
    Print( GetLastError());
}

error 4009

ERR_NOTINITIALIZED_STRING

That's not the problem, the problem is that this code returns 4 and should return 0.

Print(StringToCharArray( "ABC", array, 0, 0));
