Batch file to activate and restore an existing program if it exists, or start a new instance otherwise (in this case, Fork.exe)

fork.bat

@if (@X)==(@Y) @end /* JScript comment 

@echo off 
setlocal
for /f "tokens=2" %%i in ('tasklist /FI "IMAGENAME eq Fork.exe" ^| find /I "Fork.exe"') do set pid=%%i
if "%pid%" == "" (
    %localappdata%\Fork\Fork.exe
) else (
    cscript //E:JScript //nologo "%~f0" "%~nx0" "%pid%"
)
exit /b %errorlevel% 
endlocal
		
@if (@X)==(@Y) @end JScript comment */ 

var sh=new ActiveXObject("WScript.Shell"); 
if (sh.AppActivate(WScript.Arguments.Item(1)) == 0) {
    sh.SendKeys("% r"); 
}

With thanks!

Simpler version if you don't want all the features:

@if (@X)==(@Y) @end /*
for /f "tokens=2" %%i in ('tasklist /FI "IMAGENAME eq Zoom.exe" ^| find /I "Zoom.exe"') do set pid=%%i
cscript //E:JScript //nologo "%~f0" "%~nx0" "%pid%"	
@if (@X)==(@Y) @end */ 

var sh=new ActiveXObject("WScript.Shell"); 
sh.AppActivate(WScript.Arguments.Item(1))

How do i use this code for same batch which is running?

I don't want to call another batch file.

How to mix code ?

example

@if (@x)==(@y) @EnD /* JScript comment

@echo off
setlocal
for /f "tokens=2" %%i in ('tasklist /FI "IMAGENAME eq Fork.exe" ^| find /I "Fork.exe"') do set pid=%%i
if "%pid%" == "" (
%localappdata%\Fork\Fork.exe
) else (
cscript //E:JScript //nologo "%~f0" "%~nx0" "%pid%"
)
exit /b %errorlevel%
endlocal

@if (@x)==(@y) @EnD JScript comment */

var sh=new ActiveXObject("WScript.Shell");
if (sh.AppActivate(WScript.Arguments.Item(1)) == 0) {
sh.SendKeys("% r");
}
