[Coco] NitrOS9 L2 CoCo 3 question: Display settings/modifications

Tue Jun 14 09:23:29 EDT 2016

I compiled a NitrOS-9 survival disk including the following two scripts.

I run w.s as soon as VCC comes up, it could be put into startup.

====================================
* w.s  12/04/29 Start two new readable windows
*
*
*
windows.s var.0=12
windows.s var.0=12

* convert current window color
*
*
windows.s var.0=2
====================================
*windows.s
if %0=
t
* *** window.s ***   89/12/06
*
* Pick one of the following:
*
*  Convert current window.
*  1 - text      40x24  (16 colors)
*  2 - text      80x24  (16 colors)
*  5 - graphics 640x192 ( 2 colors)
*  6 - graphics 320x192 ( 4 colors)
*  7 - graphics 640x192 ( 4 colors)
*  8 - graphics 320x192 (16 colors)
*
*  Start new window.
* 11 - text      40x24  (16 colors)
* 12 - text      80x24  (16 colors)
* 15 - graphics 640x192 ( 2 colors)
* 16 - graphics 320x192 ( 4 colors)
* 17 - graphics 640x192 ( 4 colors)
* 18 - graphics 320x192 (16 colors)

====================================

These files and the other programs that I install and use on VCC are on my SHF888.dsk (Zip)

It is on my webpage: http://home.mindspring.com/~sfischer1/ 

The long term plan which may never be done is to install my Windows that allow up to four (4) windows on the same OS-9 Screen.

Tandy provided examples of this but they were not useful. I created asm code to build the descriptors. NitrOS-9 could with a lot of work be converted and IMHO must. I am not able to do any programming any more.
