[A83] Re: What the heck is RST???


I also meant to mention that your idea of having your own vputmap would
speed it up greatly.. if you used your own font. TI's vputmap is... shall we
say, not designed with speed in mind. personally, i'd recommend adapting
patrick davidson's fast sprite routine. it's very fast -- just about the
only thing faster is having a bunch of rotate tables hard coded into your
app, and that amount of space is hardly worth the small speed increase.

Ok, what I'm trying to do is read "basic text" files (containing
tokens) directly from flash. It needs to be done very quick, since
it needs to be translated into human readable text on the fly.

The program I've written so far handles only unarchived variables,
but even then it takes a little while to display al of the page.
So I thought having _vputmap in the program (maybe even with an
own font) would speed up the displaying process.
Since every byte is read separately I like as much speed gain as possible.

I'm also a bit reluctant of copying a selected area of the program to a
certain
part of the ram, because of the possiblity of splitting a two-byte token in
half. I'm afraid unarchiving the program wouldn't be very handy if the ram
is almost full.

Also, I like to do things the unconventional way :-)
