Re:Re: Script Reading Needed
Thanks so much. Okay.

Line 1 - good morning.
Line 2 - Enter option 1 to add.
Line 3 - option q to quit.
Line 4 - "while (loop) - Whatever is entered is not equal to q or quit.
Line 5 - do (part of while loop) - read "Enter" ? (not sure)
Line 6 - "case" - Whatever is entered, is input?? (also not sure)

The rest I understand. The punch line is that sum=$((num1 + num2)) will perform the general addition.
And the sum, sum= echo "$sum" will be sent to standard output.

esac completes "case."
done completes "while" loop.

Hope I'm close.

Thanks again,
joe.
