        Aaaaaaaaaaaaaaagggggggggghhhhhhhhhh!!!!!!
        Grauw, it's very dirty! And slow! :PPPP

        Take a look at my page, in the softwares section.
        Look for "Menu para diskette". There are two versions. One in
assembly, the other in assembly and BASIC.
        I don't remember now, but I think that the BASIC version put the
filenames in BASIC variables or, at least, in a contiguous area in RAM.
        Ok, it's in portuguese, but too few words, you can understand
easily.

        Yeah, me too.
        I also said an interesting "launcher". The program just do a FILES
on screen and use the screen as RAM. I mean, no POKE or PEEK. Just VPOKE
and VPEEK. The program used the FILES to show the directory on screen and
some VPEEKs and VPOKES to put a cursor. More VPEEKs to read the desired
filename and a RUN. Very simple.
        But this method has a problem: if the disk has too many files will
be scroll, and you'll miss the first filenames.
