B4J Question B4J&RaspBerry non-ui App: Print@, Input@, CLS, etc.

[KMatle]

Ist there a way to control the RB's prompt Screen from B4j like in DOS/QBasic where you can clear the screen, print/input @ column/row?

 

[Erel]

Mostly no.

You can use this line to clear the console:

Log(Chr(27) & "[2J" & Chr(27) & "[H")

You can also use the jColorLogger library to read console input. It allows for both synchronous and asynchronous console input. The latter means you can continue to print to Standard Out and otherwise execute code in any thread while waiting for the user to input text in the console. Also your program won't fail in the IDE (though you won't be able to do console input).
