No, your examples can be explained by how undefined variable expansion works when extensions are enabled: m The example below helps to demonstrate the issue: @echo off set "undefined=" echo %undefined:~0,10% --- OUTPUT --- ~0,10 The =:: variable actually does exist at some level on some m...

This is what i get when i try to write %=::% into a file named test12__ then try to open it:



No, seriously, i actually got that.

Opening it manually just reveals "Echo is ON", and i see that it's just 0x00. What??

Well, not so pure because you have to have a compiler. That' not a reason why it shouldn't be hybrid: Any hybrid needs another executable to use the same file in different ways. For example a typical JScript/bat hybrid needs cmd.exe (for batch) and CScript.exe/WScript.exe (for JScript). The main re...

An example of what can be done (This is a color text program, in this case): // >nul 2>&1 & @echo off int dummy0(void) { // >nul 2>&1 int i; // >nul 2>&1 & goto bat return 0; // >nul 2>&1 } // >nul 2>&1 #include <windows.h> #include <stdlib.h> int main(int argc, char* arg...

Well, not so pure because you have to have a compiler. This batch file uses tcc. Works fine for me: // >nul 2>&1 & @echo off int dummy0(void) { // >nul 2>&1 int i; // >nul 2>&1 & goto bat return 0; // >nul 2>&1 } // >nul 2>&1 #include <stdio.h> int main(void) { printf(&qu...

I'm trying to create a (very) obfuscated "Hello World!" in batch. However, this gives an error or displays nothing rather than displaying "Hello WorlD!" set/a_=5-4>nul&&set/a.=5-5>nul&&set "m=^%^t^m^p^:^~^5^,%_%%"&&set "q=%^t^m^p^:^~%.%,%_%%...

As of i know, a single batch command takes exactly 1 millisecond to execute.

This is proven when you do:

that it takes 1 second to finish.

I am making a API for Batch called "BAPI". V1.0: Currently it's only feature is "colortext" and "colortextf", a color text tool. "colortext" uses powershell, and findstr if powershell is not supported (and a error if findstr isn't around...). "colortextf&...

When i try this is the result i get: Starts a new instance of the Windows command interpreter CMD [/A | /U] [/Q] [/D] [/E:ON | /E:OFF]racter. cs. The only problem is it has a bunch of umm..'s and in the command line it acts like a single line. http://i.imgur.com/26LAy7w.png
