| Action: | The LinkNoLink command does nothing, but can set SPRM 8 to highlight a different button by setting "HH" (byte 6) to 4*button.
If "HH" is less than 4 SPRM 8 will retain its current value (and this command will truely do nothing). |
| Order: | If a compare is specified, it is performed first. If the conditions are met the LinkNoLink is executed,
doing nothing except possibly changing SPRM 8. |
| Comments: | This command is intended to be used as a cell or button command.
This command is also available as part of class 4, 5, and 6 commands, where it is more useful as a method of setting SPRM 8
in addition to the main purpose of the class 4, 5, and 6 commands. |
