To alter the icon, simply move the pointer over each enlarged 'dot' and press
EXECUTE to invert the colour of the dot. Pressing EXECUTE again will invert the dot back
to its original colour. Moving over the window, you may create an icon of your choice.
When you are satisfied, simply pick up the icon using the pointer and holding down
the MOVE button, 'drag' it to any of the icon positions in the UPPERMOST icon store: On
releasing the MOVE button, the icon will be stored in the selected position,
OVERWRITING the icon previously stored at that point: REMEMBER, created icons may
only be stored in the UPPER icon store, and must be stored there before going on to any
other operation.
To the right of the icon designing window is a gridded window which enables you to
assemble several icons together to see how they look. Simply pick up the required icons
one by one from any of the two icon stores at the base of the screen, and deposit them in
the required positions on the grid: If you wish you may move them around the grid you
may pick them up and relocate them. If you pick up the wrong icon, simply move over the "
dustbin" icon and release the MOVE button.
You may also assemble a set of icons by combining the main and alternative icons
into the upper icons store, saving under a new filename.
When you wish to create a new set of icons, remember they must be stored in the
uppermost icon store first. To save these, simply move the pointer over the disc drive icon,
press EXECUTE: This will reveal the filing prompts in the MESSAGES window. Select "
Save icons" by moving the pointer over the prompt and pressing EXECUTE: When
prompted, type in your selected filename followed by <RETURN> . Your set of icons will
now be saved onto your current filing system (disc/tape).
You may create as many sets of icons as you wish, taking care to save them under
separate filenames. These may then be used in conjunction with the ROM routines
*DEFINE (see 5:4) and *ICON (see 5.7).
When using the *ICON command with an icon number between 32 and 95, the built
in icons are used. These icons are used in various programs such as ICON DESIGNER
and the MENU program, and other software to follow.
These sixty-four icons are shown in figure 5 and are filed in two set as R.CHARS1
and R.CHARS2: Note that icons 80 to 91 are designed for use with the *POINTER
command and are in pairs, each icon followed by its mask.
