[Oberon] Module aliases - what is the correct way to handle them

[Joerg]

Tomas

Debug output could be coded like this
    IMPORT Out, Debug := Out;
and all your debug output like Debug.Str(“packet sent“) appears on screen.

A „stub“ of Out looks like this

MODULE OutStub;

PROCEDURE Char*(ch: CHAR); END Char;
PROCEDURE String*(s: ARRAY OF CHAR);
  END String;
PROCEDURE Int*(i, n: INTEGER); END Int;
PROCEDURE Ln*; END Ln;

END OutStub;

if you want to use it, you write

IMPORT Out, Debug := OutStub;

and „magically“ all your debug ouput is not written to screen.
