B02) How do you read and write text in BETA?

Texts are written onto standard output by:

'hello'->screen.puttext;

which writes the string 'hello' on the screen at current cursor position.

'hello'->screen.putline;

also writes a carriage-return.

Integers are written by:

7->screen.putInt;

If you want to write onto other text variables (such as t: @text), you can
do it by:

   'hello'->t.puttext;
   'hello'->t.putline;
   7->t.putInt;

Reading texts is equally easy:

keyboard.getline->s[];

reads a line of text from the keyboard, and assigns a reference to the read
text to the text reference s (assumed to be declared as s: ^text).

Reading from other texts (e.g. t) is done by:

t.getline->s[];
