[Oberon] Re (2): Re (2): The Out module.

[Jörg Straube]

I use Out in all my programs in ProjectOberon. This is the reason why I found out, that the huge amount of Texts.Append() in the original implementation will eat up a lot of memory.
BTW: I added printf() to my Out.Mod to further simplify output capability.

I used a BOOLEAN variable and the different output procedures follow this example:

PROCEDURE String(s: ARRAY OF CHAR);
BEGIN Texts.WriteString(W, s); Append END String;
