Hi.

I'm trying to write a simulation which saves/opens a data file containing the current state of the simulation. However, I want the user to input the filename. I've been able to use JOptionPane to prompt at the beginning, with the line:

String Location = javax.swing.JOptionPane.showInputDialog("File Location");

in setup. However, this doesn't work when I try to use it in the middle of the simulation - the program locks up and I have to kill the process. Is there a way to have a popup dialog where I can input text, or just a way to input text in general. I guess I want to avoid swing...

On a side note, some browsing on the forums tells me that swing and Processing don't work all that well together, along with lots of posts of "check the tutorial." I have been unable to locate this tutorial...can someone link?

Thanks
