Add more library functions

[boriel]

Thanks, Boriel.

Part of the duplication issue is lack of documentation - not knowing what's out there as a callable function.

Think that should be in library routines? I suppose knowing what's available in what include is going to help a lot

E.g. the print42 library is buggy. It contains the following code:

Code:

newline:
        LD DE,(63536)
        CALL nxtline       ; move to next line
        LD (63536),DE     ; and go on to next character
        JR nextChar

This is a bug for sure: you're writing at a fixed position (65356) which is the memory heap for temporary work, so you're corrupting it. Besides, I don't understand very well what these lines do? :?:
