Simple User-Input AKA a DOS application.
I've been doing some programming using the simple DOS commands, and reading keyboard input to read strings into variables.
I've got an Applet at the moment with a text area (several rows high), and a text field (single line), and I've got the text area reading a string variable into it, and the text field appending it's value to the variable on the event that you hit enter..
But the issue I'm having is that, unlike the DOS commands, I can't get the processing to stop and wait for an input, then continue...
If anyone could help out, it would be great, Thanks!
Here's my code at the moment... the commented out lines in the input class are wherre im playing around at the moment...
Any help or references appreciated.
Thanks :)
