NEED HELP FROM QBASIC GURUS!
« on: January 27, 2003, 08:34:14 PM »
How do you plot a pixel using the OUT command in Qbasic? :-?  My gool is to have control of the pixel using the CRTC. The OUT command is also alot faster then  using call absolute... Also using DEF DEG = &HA000 and POKE will not work with all computers.

PSET will not work in svga graphics modes.
I use QBASIC becuse I can download for free from Microsofts webpage as part of olddos.zip and I can program large programs in a short amout of time. The code also make great programming docs.

03C0h/03C1h = Attribute controller
03C3h = Video Subsystem Enable Register
03C4h = Sequencer
03C6h = PEL Mask (although I tihnk PEL stands for Pixel or Palette, so I dunno...)
03C7h = for Read is the DAC State Register, for Write is PEL Address Read Mode
03C8h = PEL Address Write Mode
03C9h = PEL Data Register
03CAh = for Read is the Feature Control Register, for Write is Graphics 2 Position (sometihng for EGA, Idunno what it means)...
03CEh = the Graphics controller
03D4h = CRTC
03DAh = for Read is input status #1 register and for Write the feature conrol register, similar to 03CAh
