User guide

If the icon number is from 32 to 95 the Icon definition stored in ROM is used to
redefine ICON 0. Icon 0 is then displayed on the screen as usual. Since icon 0 is constantly
redefined by the ROM it should not be defined as a user icon.
With the computer in its normal state there is a limit of 8 ICONS which can be
defined by the user, there being 0 to 7. Any other icon number between 8 and 31 will give
the same result as icons 0 to 7:
To allow more icons to be defined the character set will have to be exploded and
PAGE set to a new value:
Icon No. New PAGE
*FX 20,0 0 to 7 no change
*FX 20,1 0 to 15 PAGE = PAGE + 256
*FX 20,2 0 to 23 PAGE = PAGE + 512
*FX 20,3 0 to 31 PAGE = PAGE + 768
e.g: To use 16 icons
*FX 20,1
PAGE=PAGE+256
*DEFINE CHARS
CHAIN "PR0GRAM"
Note: If Computer Concepts Graphic ROM is enabled a *GFX 5 command must be
issued to allow icons to be used.
e.g. *MC. ON
After a *MCURSOR OFF command, moving the Mouse changes the coordinate as
used by OSWORD 64, *SHOWPOINTER, and *MOVEPOINTER. Therefore these
commands must be preceeded by a *MCURSOR OFF.
When *MCURSOR ON is used, instead of generating co-ordinates, the ROM
converts the Mouse's movement into cursor keys. This mode is therefore intended for use
in existing programs such as VIEW, which use the cursor keys for movement.
