CASLrt is a visual programming environment that makes the creation of any kind of Palm OS system application easier.
It is a complete tool pack that lets you create applications both visually and by using the necessary Visual Basic-like commands.
Once you have finished the applications, CASLrt allows you to compile them and run them from your own PC in order to verify that they are working correctly.
As soon as the application is done, with one simple click on the compilation, you can run a sync to transmit it to your PDA.
A basic programming environment with great resources.
