Thanks Laszlo for pointing that out. It appears that the rand() function is
implemented on 32 bits in UEFI StdLib, instead of 16 bits as I was expecting.
In this case the generated numbers are correct.

The expression evaluator must use the actual string values, as you expect.
Section 28.2.5.7.4 says that a string value in an expression is a
"Null-terminated string" not a string ID.
Furthermore, some operations, like Mid() and Token() actually create new string
values. Which string id
HII has a number of opcodes which can push/pop string values on the HII
expression stack (like the opcodes in the list below). The language in the UEFI
spec made me think that form processors push/pop the actual strings (not HII
string IDs). However, after looking at the EDK2 browser code I get
Tim,
Thanks! In that case I'll either have to become a unicode expert and make
my own fonts or I'll hack it by using bitmaps as my letters. I think I'm
just going to use bitmaps :)

Hi,
I am trying to generate random numbers in UEFI. For this I am using the StdLib
wrapper in order to call rand() function. The problem I am having is that I am
expecting that the generated random number to be in the [0, RAND_MAX) range,
but the generated number is way bigger than that.
