So open a file called a and we can start First we need to require the robot api. That will allow you to gain more OpenComputers knowledge yourself, And when you do find something you 100 cant figure out without help is went you should ask around on irc. There are a few differences, which you can look up here: differences in the standard libraries. The best thing for you to do Is to convert it yourself one line at a time. But it's not quite what I wanted, and it resets if the system is turned off. OpenComputers makes an effort to largely emulate the standard library in areas that would usually interact with the host system - that being the I/O library. ![]() a local file io.open('/tmp/foo.txt', 'w') file:write('abc', 'def', ' ') file: close () - foo.txt now has 'abcdef ' b:lines ( lineformats.
