Constants with same name in different functions (UE1)

The UE1 compiler UCC.EXE does not support constants with the same name in different functions.

Example:

class test expands Object;

function Nothing1() {
const CDebug = true;
        return;
}

function Nothing2() {
const CDebug = true;
        return;
}

On compiling this, a GPF occurs:

Parsing Test General protection fault!

That's because it doesn't really apply the scpoing concept to constants. They are always global to the class. —Wormbo 00:11, 19 November 2015 (EST)

I did not find any scope description in the article - therefore I found it worth to mention here. (BTW: UScript is the first language I saw where the scope of local definitions extends that area.) --SeriousBarbie (talk) 00:29, 19 November 2015 (EST)

Well, the UnrealScript compiler is really basic compared to other languages - and it's written in really messy code. All these weird things are essentially compiler bugs. —Wormbo 10:28, 20 November 2015 (EST)
