The Modify Character Attributes in a Touchkey command causes the character attributes within
a touchkey to be modified on a touchkey basis, rather than character-by-character.
This command assigns to the designated touchkey the character attributes currently in effect (as
last assigned by the Set Character Attributes command). Because the Modify Character
Attributes in a Touchkey command directly causes attributes to be modified, the NOCHANGE
Attribute Mode has no effect on this command.
NOTE
If the Set Character Attributes command has selected the conceal attribute, characters within the touchkey
disappear. The characters can be made visible again by sending the Reverse Character Attributes in a
Touchkey command to reverse (turn off) the conceal attribute.
For the color TCS to properly conceal characters, the conceal color attribute must be set to the same color
as the screen background.
The area of the display affected by this command is restricted to lie within the scrolling region
when Origin Mode is set.
Within a touchkey, the host can restrict the effect of this command to one of the areas previously
defined in this chapter under Touchkey Visual Extent.
For the Modify Character Attributes in a Touchkey command to produce correct and predictable
results, the touchkey’s line type must be determined. Line type is determined according to the
following rules:
•
If the touchkey contains any double-size lines, the entire touchkey is assumed to be
composed of double-size lines.
•
If the touchkey contains any double-width lines, the entire touchkey is assumed to be
composed of double-width lines.
•
If the touchkey does not contain any double-width or double-size lines, the touchkey is
assumed to be composed of all normal lines.
NOTE
Undesirable results may be produced if the Modify Character Attributes in a Touchkey command is
executed on a touchkey that contains mixed line types.
If the touchkey specified in this command designates a touch cell within a touchkey (but not the
master cell), the attributes are modified within that touch cell rather than the entire touchkey.
