endless

This software program is based on the well-known problem “Towers of Hanoi”.

The program is created to demonstrate ReXX program’s flexibility and portability.

You are encouraged to modify this program to make it run on your ReXX interpreter, on the device you are using.

To make sure that it is maintained properly, I am inviting you to send me your modifications which I will apply on my copy and release it back to more people.

Click here to download it, then unzip and run this software program, as is. If the unzipped file “endless.rex” does not run as prescribed, with your help, we may be able to make it work with the ReXX interpreter and the device you are using.
