Why you just do not extract the body of the for cycle into a separate function? Then you can do the funny stuff in the extracted function.
void DrawScaleX(HDC dc, int step, int x0, int x1, int y0, int y1)

for(int x = x0; x < x1; x += step)

Steve's answer works. The problem with your attempt to reproduce ESV's script is that you're using `$input`, which is a reserved variable (it automatically collects multiple piped input into a single variable).

Especially with .NET 2.0 many things have changed in the .NET framework (not only at the language level). You will need version 1.1 to run programs linked against that version.

`id` is a built-in function that gives the memory address of an object. If you name one of your functions `id`, you will have to say `__builtins__.id` to get the original. Renaming `id` globally is confusing in anything but a small script.

If you don't mind using the Windows API, you could use EnumWindowsProc, and check each of the handles that that turns up using GetWindowThreadProcessId (to see that it's in your process), and then maybe IsWindowVisible, GetWindowCaption and GetWindowTextLength to determine which hWnd in your process is the one you want... |

Well, an obvious "solution" would be to make a single function and add one extra parameter (of enum-like type). And then do an if() or switch() inside, and perform the appropriate actions. Because hey, the *functionality* of the functions is different, so you have to do those different actions *somewhere*.

I think I'd move:
MoveToEx(dc, x0, y, NULL);

Knowledge management is crucial. As you already plan to use wiki (like [Trac](trac.edgewall.org) or [Redmine](http://www.redmine.org/)) you could use it for KM as well.

Instead of telling the game class there is only ever one human, why not let it get that input during the menu/initialization of the game? If there are more players, that can be decided via some form of input (select players in the menu), prior to the game class initialization. |
