Where this length comes from?<br>
Well, I tested String on windows xp, and
found that 1023 was the limit, when given a
number bigger than that, the output kept the
length of 1023.<br>

</span> Can you add this too as a test? In some compact

<div>I tried again and I found that maybe you were right.
The number of 1023 was got like this: I wrote vbscript
with a common text editor on xp, and save it as xx.vbs,
then double clicked it. I used this method and found that
MsgBox String(1024, 65) only printed "a...(the length is
1023)....a".</div>
<div>Tragedy is today I write MsgBox Len(String(1024, 65)),
and it prints 1024! It's the same with the other numbers
greater than 1023! So I was cheated yesterday. The true
limit may be 32768 * 16384 * 1.25， but I am not sure. I
need to know the exact limit of the length of the string
subtype, however experiments show difference with the
documents of microsoft which claims the limit is about 2
billion.</div>

In that case we don't care about exact limit if any. Just allocate
what's requested and fail with proper error code if allocation
failed.<br>
