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.Thanks for commenting.

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.
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".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.
