1. Prompts the user for a number.
2. Prompts the user for an operation (add, subtract, divide or multiply)
3. Prompts the user for a number.
4. Prompts the user for another operation (same as above) OR the option to get the result for the equation.
5. The script should loop back if the user chooses to add another operation, and ask for another number (repeat until result)
Now, i already have the arithmetic sorted, and i know i have to add an UNTIL loop, but i'm not very good with loops as i find them hard to understand.
Here is a copy of my code so far:

Can anyone give me any pointers? I really have tried to look for solutions but this is my last hope. ANTHING WILL HELP. THanks

Reason: Please use code tags for data and code samples, thank you
Here are a couple of examples that should illustrate enough to get you going. You should be able to figure out how to 'plug' your code into a loop like one of these:
Using as much of the orginal code as possible we can create a simple "while true loop around the decision whether to quit or do another calculation. We enter the value for $n1 once at the top of the script and from that point on seed $n1 with the value of a running total in $total.
The modified script keeps on asking for more calculation on the running total until the user presses carriage-return.
You could add a line just before "break" to display "Final total is $total" if that is a requirement.
Try it and enjoy.

Hello,
I'm trying to write a while loop for a decimal value in tcsh which I know can't be done. Instead I want my increments to be one order of magnitude too large and then divide it by 10 when I use the variable. However, I don't know how to divide my variable and set it as another.
