[is there a way to make a batch script display the variable name instea]

Hello, i am making a batch script that will install another batch script. It looks like this:

@echo off

echo @echo off > example.bat

echo echo Hi >> example.bat

echo echo 1.) Option1 >> example.bat

echo echo 2.) Option2 >> example.bat

echo echo 3.) Option3 >> example.bat

echo if %selection%==1 goto opt1 >> example.bat

echo if %selection%==2 goto opt2 >> example.bat

echo if %selection%==3 goto opt3 >> example.bat

So it displays all this text and saves what is displayed to example.bat. But it will display variables as their values; instead of making this:

if %selection%==1 goto opt1

it will do this:

if ==1 goto opt1

because theese variables have no value. So, is there a way to tell this script to display variable names instead of values?

p.s.

also, a pause message is "Press any key to continue..." . Can i change that?
