Pattern Display Fields
The pattern display field displays the alpha-numeric bit pattern specified for
each X and O marker in all designated labels. The bit pattern is displayed in
the same numeric base and same order as the data listing. When the pattern
display field is highlighted, the front-panel keypad is used to set the bit
pattern.
When there are more labels assigned than can be displayed in a single screen,
the pattern display fields are rolled back on screen by the
Label/Base roll field.
See Also "Label/Base Roll Field" in the Common Menu Fields chapter for a complete
definition of the Label and Base roll function.
