Hello,
i have setup a system to get items from computer via rednet and redpower. However it works. But there is an issue i would like to find a better solution.
I use tables to print a options menu. But if i use more options then the terminal can hold the menu mess up and the program don't work anymore. I want a "NEXT PAGE" Button to print more options. I can do it with shell.run page2 but i asking if there is a better way to putt all my options in one code.
I'm new to lua and i use and change the code from another forum user here. Thank for that!
Regards
Here is my code for the host:
