Notes
This system call was introduced in OZ V4.2, and is used internally by OZ to create all application & popdown windows. It avoids the VDU clutter that otherwise is necessary to draw windows in OZ.
Example of window definition block with extended window "2" having 8 pixel banner and bottom line:
Code Block | ||
---|---|---|
| ||
DEFB @11100000 | 2 DEFW $0000 DEFW $0811 DEFW bannerptr ; this points to a banner text, null-terminated. |
