1. Please help a newbie with SVGA ... :)
Hiyas ... I'm new to Euphoria, but not to programming in general ...
that is, I have limited experience with some other programming languages
...
Anywho. My problem is with the SVGA modes, 256+. I can't get any of them
to work! Whenever I try to use them, ie with graphics_mode(), I can only
use the top 1/3 of the screen ... the rest is unaccessable. I have no
idea why this is ... I can use SVGA modes on various other things, like
games, so I know it isn't my graphics card. It's a ATI Rage II with
2megs of RAM, if that matters.
I tried using Univbe VESA and use_vesa(), but that gave me an illegal
operation under Win95 ... so I rebooted to DOS mode, and it locked up my
system rather soundly, so I had to reboot.
Any ideas? I'd rather not be stuck using mode19 for everything. :) (That
works fine, btw, as do every other graphics mode.)
Thanks. Bye! :)

Darren,
First of all, welcome to the list. I'm curious as to your impressio=
ns
of Euphoria as compared to other languages. Impressed yet?
Now to the substance of your question. I had the same difficulty. =
I
tried use_vesa() and some so-called universal vesa drivers, no effect. I=
did not get an error, though. Because I did not have need for it at that=
time, and due to the presence of other projects, I dropped the issue.
Apparently, there are people here who have made SVGA work. A fellow=
Euphorian (Monty King) recommended that I get hmmm...let me look...get a
new card. What kind of video card do you have? If you get an error in
Windows, consider calling technical support. My video card once interfer=
ed
with Sound Blaster TextAssist (don't ask (g)).
Anyway, it was implied that a S3-3dX 4mb card with EDO ram works. I=
don't know.

I am of the opinion that it shouldn't be that now. An ati rage pro should
give great peformance under vesa 2.0, although I don't know how compliant it
is. My new card (that I replaced the s3 with) is a jaton AGP card with 4
megs sgram and a trident 3dimage chipset, and it works great also. In fact
it blows the s3 all to h#ll. I could barely play unreal in like300x400 or
so mode (not remembering the numbers, but small) and this Jaton card will
run at 800x600 no problem, and playably with 32 bit color textures.
>Anyway, it was implied that a S3-3dX 4mb card with EDO ram works...
It was quite vesa compatible, it just didn't perform that well. It was
barely adequate pefrmance wise (having seen the comparison now) in win95.
Of course I have recently installed direct x 6 core also, and am running
direct x 5 before that. I think that these things allow various graphics
modes to be accessed by dos apps.

Hi Darren
Welcome to the list. I had the same problem with my machine. When I used
'use_vesa()' I then got a full screen but none of the SVGA mouse routines
I'd down load from the web would work properly. The mouse left a trail and
messed up the screen.
Rob told me there was a problem with some ATI cards and suggested trying
Display Doctor and give me some other advice but I couldn't obtain much
improvement. In the end I took my graphics card out and swooped it for a
different make. The computer shop took the ATI in part exchange so it didn't
work out to expensive.
The only thing I've noticed now is when in a SVGA mode graphic plotting at
the top two inches of the screen is very fast, where as the remaining potion
of the screen is about five times slower. Dose anyone know why this is?
Hope this helps a bit.
Regards,
Roy

My guess is that you are missing the correct DOS driver. Apparently, some
manufacturers are a bit lazy about giving out the correct drivers for DOS,
on the assumption that you will only be running Windows, and so those
drivers will work just fine. You could check the video card manufacturer's
site to see if you have the most current driver.
If that fails, a good option is Scitech's Display Doctor. You can download a
trial copy at:

Just a word of warning: I installed Display Doctor on my home machine about
two months ago, I cannot even remember why. It worked ok, but at the end of
the trial period it simply left my machine in 640x480 resolution with 16
colors only and everything else gone. I tried to reinstall the original
drivers to no avail, eventually I had to erase everything and rebuild the
system - a wasted weekend. jiri

I myself have an Ati Rage Pro, however it seems Win98 defaults to Ati Rage
II for the drivers.
If you go to www.atitech.com you can find the latest win95 and win98
drivers, beta openGL icd (about time.. but they still got to get it to work
with Unreal, of which the OpenGL is still in Alpha fase). But most
interestingly they have an Vesa program esspecially designed for Ati
programs, which (for me) helped me to get a few SVGA programs running that
used Pete's Mighty.e (the demo program of Irv's WindoZ was all screwed up on
the screen)

Get the specific univbe dos driver and use use_vesa () if that really really
doesnt work, then you can go back to the shop with it.
Good luck with your Euphoric experience 
and with your Ati-card..
(the performance is really ok, but their support of OpenGL: slow and not
holding up to the 3D-fx standard makes it pretty annoying to me, the reason
I have it, was that it was bunndled with my pc, marketing.. yak what do I
hate that word, its eating up this world, people producing nothing other
than brainwashing material.. oh well.. enough wining..
BTW David, I kind of agree with you about the dots, only im allergic to
dots, they remind me of all kinds of weird java and cpp trauma's. Cant we
use ',' or '~' ?

I've had similar problems with my S3 card
in the past. For me the solution was simple.
I installed the latest version of directX.
I now relativly good performance out of a
pretty old card in all modes.
