in order to do it's magic, CRT must control the terminal.
Are there alternative ways to write something on the screen and to clear the
screen?
For example with unit system?
In the general case, that's going to be terminal-specific. If you only
want stdout (and/or stderr) output you'd need to know what escape
sequence to sent to the terminal (possibly with reference to
termcap/terminfo- I don't know whether there are libraries to handle
this) but if you wanted full control like you get with the FP IDE I
think you'd be using the old TurboPower stuff.
In extremis, if you're already invoking an external program and want to
clear output after it runs, and if you know that you're running on a
unix, you could simply invoke the clear program.
Going back to your original question, I see no reason why you couldn't
open and parse e.g. /proc/partitions as an ordinary text file.
