Check your PATH environment variable:

        echo $PATH

If you want your script to run when you enter its unqualified name, your PATH
needs to contain either an entry for /SYS/CARL, or the current working
directory indicated by a single period (.) character.

Some people consider . in PATH to be a security risk because when you cd into a
new directory, and then try to run an unqualified command name, you may find
yourself surprised if that directory contains that command where somebody
implemented different functionality.

PS: "test" is a bad choice for a file name because it conflicts with a shell
command called "test".
