case selection help request

Hi all, I am new to this forum as well as SPSS. I currently have a dataset in which a variable of mine has numbers 0-10 and several strings that are important exceptions. I am looking to run tests on the numeric section only and I am looking for advice.

My current ideas are to 1) use the 'Select Cases...' function under the 'Data' tab on the variable directly, or 2) to create another variable that is essentially x=1 if number and x=0 if string, and then use the 'Select Cases...' function on that variable.

Any help is welcome including resources to learn more about syntax itself. I currently look through the IBM SPSS Syntax Reference, but I'm hoping there is something more straight forward.

Thanks in advance!
