Exception handling

[Moedig]

Hi guys, Basically i just wondered if someone could explain to me how it is possible to return to the start of the try block after an exception has been caught.
I have

try{
//method for user input
}
catch (exception definition) {
//exception message when user inputs wrong type of data etc
}

but id like it to return to the start of the try block to allow the user to re-enter the correct data... is this possible? please help,

greatly appreciated,
Moedig

There isn't a way to jump back up to a certain line of code. You'll need to use functions or loops to achieve what you want.

Example using a loop:

declare a boolean
while input is invalid {
    try {
        get user input which might throw exception
        flag input as valid
    } catch exception {
        display error message
    }
}

If the user input throws an exception then it will jump the line which marks the input as valid. Then it will go around the loop again.
