I'm having trouble using the logic 'not' operator. I tried looking up the docs and also had a quick look-around in the forum but I couldn't find any examples. I'm basically writing code as in the following: void myFunc() { bool b = false; if (!b) { // do something here } } The AS compiler fails on the (!) symbol saying that it is an unsupported operation for the datatype. I tried using "not" but to no avail. I am assuming here that (!) and (not) are equivalent tokens since (&&) and (||) and interchangable with (and) and (or) respectively. Am I doing something wrong? P.S. I'm using the stable version but I did not have the opportunity to try this out with an earlier stable or WIP version. Platform is Win32.

You've found a bug in the library. I'm looking in to it right now.

This bug was introduced when I added const for objects.

You can fix it by changing line 4537 in as_compiler.cpp, function CompileExpressionPreOp() to:

if( ctx->type.dataType.IsEqualExceptConst(asCDataType(ttBool, true, false)) )

instead of:

if( ctx->type.dataType == asCDataType(ttBool, true, false) )

Thanks for discovering this bug.
