Hello List! I've successfully built latest version with the same results of test suite like other people already have written. Range-checking is a really cool (great thanks to developers:))! It appears now new warning that I didn't see before (warning: Operand with side-effects is not evaluated). It isn't described in the documentation. It points to strings that look like: LocalVariable := GlobalVariable mod GlobalConst; Can I do something to avoid it? What does it mean? It means that the value evaluated will not be assigned to LocalVariable? Or it means that Global variable will not change its value as a result of this activity?
