while loop exit
i wrote a while script as part of a huge program. this script, once picked, begins to output data to the person using it. pretty easy, as the person doesn't have to keep typing commands to get the output that the while loop automatically throws out.

now, the thing is, while this while-script is outputing data the only way for the client to exit out of the script is to Control-C out of it. and when they do, that Control-C not only kicks em out the while-script, it also kicks em out of the program that the while-script is in there by causing the client to have to restart the program?

is there anything i can add to this while-script that will give the user the option to exit out of it without havint to control-c?
