I write these script codes uint8 test(uint8 s) { return s; } void main() { test(0X1); ( X is capital letter) } the Compiler of AS 2.10.0 will show the results: [compiler] New 0.as (7) : Error : Expected ')' or ',' I think, maybe AngelScript Compiler just only recognise hex number with 0x prefix. But, in C/C++, the prifix with 0x or 0X will be identified as Hex Number. Is this a bug ? or just author's thought? Thanks a lot.

Hmm, I've always used a lowercase x to define hexadecimal numbers. Why not go with that?

I always use 0x too. It never occurred to me to support 0X as well, but I guess that can be done.

Just to let you know, hexadecimal constants with 0X is supported. In fact it already was, I had just forgotten about it.

I tried to reproduce the problem, but I'm not getting the compiler message that you're getting. Can you give me another example that reproduces the problem?
