I'm writing a macro and is trying to use either lambda or fn to create callable sub-routines
but find that ESC-functions like GetCursor() and Find() is not available in either.

If I put all the code in the macro itself it works fine, but has a lot of repeating code.

1. What must I do to have access to the ESC-functions within either a lambda or an fn?

2. Also, what is the 'instance' refered to in:
Quote:

. lambda(args) ! instance | Invokes lambda, using instance as instance for lambda execution (accessible via .name or self).

Below demonstrates the issue:

macro "PROBLEM" Ctrl+F8
{
	ClearConsole();
	cp = GetCursor();
	A = "STD";
	B = "COUT";
	
	//this works fine...
	#:cat(a, b, &x) { x = a + ">>>>>" + b; }
	
	c = "error";
	:cat(A, B, c);
	cout(c);
	
	
	//this fails with: [..] 'SetCursor' is not a lambda
	#:test(a, b)
	{
		SetCursor(0);
		if (Find("std::cout", 1, 1))
		{
			f = GetSelBegin();
			l = GetSelCount();
			SetCursor(f);
			Remove(l);
			s = a + "::" + b;
			Insert(s);
		}
	}
	
	:test(A, B);
	SetCursor(cp);
	
}

thx
