Windows Batch loop all variables with findstr

In my Windows batch file I have a various amount of variables. Lets say I have the following variables:

set varTest1=test1
set varTest2=test2
set otherVar=variable500
set varS=string
set yetAnotherVar=foo

They do really make no sense buts thats not the point. I am looking for a method that prints out all values of variables that start with var: So when I run my batch with a certain help parameter it should print out all three variables starting with var and its value. The output could look like this:

These are the available variables:
varTest1 : test1
varTest2 : test2
varS : string

I created the following for reading the parameter:

IF "%1" == "" ( 
echo No help parameter was set. Program will exit. ) ELSE ( 
IF "%1" == "help" ( 
call :showAllAvailableVars ) ELSE (
echo Do something else))

Now I would have my method 

:showAllAvailableVars

I think the solution could be something with the findstr method but I could not figure it out how to do that because findstr is mainly for files and not for searching through own program variables.

You could use set var to print all variables which begins with var.
See also set /?

Create array instead of different variables. Like,

set var[0]=test1

set var[1]=test2

set var[2]=string

then in your 'showAllAvailableVars' function do this

for /L %%i in (1,1,%n%) do echo !var[%%i]!
