Thank you, it has helped. But the visual tester can't run in this beta, just in case.

up: is there no function to rollback from beta to release? that would be handy.

Compilation error

It compiled fine before - no error

A100:

Compilation error

It was compiling all right before - no error

I had that when I ran out of disk space.

Vladimir Pastushak:

This happened to me when I ran out of disk space.

There is more than enough free space - after several unsuccessful attempts I saved the compiled file in the same folder under a different name and everything was normal. The .ex5 file itself of the previous version (script) runs fine as well - no errors

Compilation error not corrected

template<typename T>
class A {
public:
        void f( int ) {}      //(1)
};
class B : public A<int> {
public:
        void f( int, int ) {} //(2)
};
void OnStart()
{
        B b;
        b.A<int>::f( 1 ); //Error: 'A' - undeclared identifier
}

A contradictory result:

So you've 'gone beyond' ULONG

Print(string(ULONG_MAX));

Yes, found a non-obvious rule that in case of overflow the extreme value is returned

If Expert is converted to Indicator, then after recompiling, at least the standard icon in the Navigator window does not change immediately, but only after restarting the Terminal. The Refresh menu in the same place - does not help

Expected: immediately
