   A better way to set up the ANSI char would be as follows:

   for /F “tokens=1,2 delims=#” %%a in (‘”prompt #$H#$E# & echo on & for %%b in (1) do rem”‘) do (
   set ESC=%%b
   exit /B 0
   )

   You can then simply use something like this:
   echo. %ESC%[31mERROR%ESC%[30m

   or is you still want to keep your vars then:
   echo. %red%ERROR%default%

   For example:

   @echo off &cls
   setlocal

   rem ANSI Colors
   call :setESC

   set red=%ESC%[31m
   set green=%ESC%[32m
   set default=%ESC%[0m

   rem Domain names or IPs
   set hosts[0]=192.168.0.1
   set hosts[1]=google.com
   set hosts[2]=bbc.co.uk

   rem Human-friendly names (optional)
   set names[0]=Router –
   set names[1]=Google –
   set names[2]=BBC –

   :startover
   set /p “hosts[0]=Router IP address or [ENTER] for default (%hosts[0]%): ”

   :loophosts
   echo,
   echo Checking hosts…
   echo,
   REM If you add more hosts above then alter the following to match:
   for /l %%i in (0,1,2) do (
   call :pinghost %%i
   )
   echo,
   choice /M “Check hosts again?”
   if %errorlevel% == 1 goto :startover
   exit /B %errorlevel%

   :pinghost
   setlocal EnableDelayedExpansion
   set j=%~1
   @ping !hosts[%j%]! -n 1 -w 1000 | FIND “TTL=” >nul
   if %errorlevel% == 0 (
   if “!names[%j%]!” == “” (
   echo !hosts[%j%]! %green%Online%default%
   ) else (
   echo !names[%j%]! %green%Online%default%
   )
   ) else (
   if “!names[%j%]!” == “” (
   echo !hosts[%j%]! %red%OFFLINE%default%
   ) else (
   echo !names[%j%]! %red%OFFLINE%default%
   )
   )
   exit /B 0

   :setESC
   for /F “tokens=1,2 delims=#” %%a in (‘”prompt #$H#$E# & echo on & for %%b in (1) do rem”‘) do (
   set ESC=%%b
   exit /B 0
   )

   Didn’t run your code, but looks okay to me. Always open to alternative methods. Thanks!
