Batch File Syntax Help

I've made a script to help me get past some restrictions at my school and I've been experimenting with the syntax for the 'if' test.

Here's some code that is somewhat similar to what I want:

Code:

@echo off
:temp
cls
echo type 's' to echo string
set /p ch=
    if %ch%==(s S) (
        goto hello
    )
cls
echo Not a valid paremeter
pause
goto temp

:hello
cls
echo hello
pause
goto temp

Basically I want my script to accept both upper and lower cases. So if I type 's' or 'S', it will do whatever is nested under the if block. And if the input is anything other than 'S' or 's', it will loop back to the temp location.

I know that if I type it as:

Code:

set /p ch=
    if %ch%==s (
        goto hello
    )
cls

it works; as I've been doing with my script so far.

My question is, how would I be able write the if command so that it will do whatever is nested under it regardless of whether the case is upper or lower?

Thanks.

Edit: I just realized that I can use the 'else' statement to fall back on, instead of my 'manual' method.

you just need the /I switch on your if statement which does case insensitive comparisons of the string e.g.

if /I %ch%==s goto hello

Thanks a lot for that, it helped solve my problem. I guess I didn't read the 'if /?' 'man' page, if you will, correctly.
