^EG o ~EG (Erase Downloaded Graphic)
This command deletes all the images contained in the RAM memory.
3.1.8 Advanced commands
All commands that are sufficient for printing in CZL emulation have been described in the
preceding sections. Several advanced commands are described here so that the user can take full
advantage of all the features of the machine, achieve special effects, and/or optimize its
performance.
3.1.8.1 Comments
^FXaa…a (Comment)
This command is used when clarifying comments must be inserted in the printing program.
Comments inserted in this way do not have any effect on the printed label.
aa…a is an alphanumeric comment string.
Whatever is written between the ^FX command and the following character ^ (o ~) has no effect on
the printed label: its only function is to introduce a comment string for future reference and greater
program clarity.
It is good practice to use these comments for the preparation of basic documentation that will
simplify subsequent program maintenance.
3.1.8.2 Graphic effects
^FR (Field Reverse Print)
It is possible to write some fields in reverse to highlight them: they appear in white against a black
background instead of black on a white background. More generally, what is black becomes white
and what is white becomes black.
Refer to section 5.3 on page 55 where two examples of labels in reverse are described.
To produce this effect, a black box of the desired dimensions must be provided (see the ^GB
command on page 29) superimposed on the field in question. As a result, the black of the box is
superimposed on the black of the writing according to the OR
157 mode and the field is “deleted”
from the box.
With the command ^FR the mode of the current field is locally changed to XOR
158 until the next ^FS
(or ^XZ) command. The resulting effect is of a field in reverse whose colors are inverted. More
generally, where the field is superimposed on another, the color becomes white.
157
OR mode means that black on black produces the result black (black + black = black), just as black + white = black.
158
XOR mode means that black on black produces the result white (black
⊕ black = white), just as black ⊕ white =
black.
