Channel Range
Most commands will execute against either a single channel or a number of channels. Where the command is executing against a number of channels we call this a range. The range does not need to be made solely of consecutive channels.
A channel range is made up by using channel numbers and 3 possible modifiers :
A simple range would be to use 2 or more channels, to do this you use the '+' modifier to join them :
1 + 2
| = 1,2
|
1 + 2 + 3
| = 1,2,3
|
Where the range is to be made up of consecutive numbers you may use the 'Thru' modifier. This selects all channel numbers inclusive :
1 Thru 5
| = 1,2,3,4,5
|
7 Thru 9
| = 7,8,9
|
You can press 'Thru' a second time to automatically select the last channel. For instance the command 1 Thru Thru ON would turn all channels on.
You can also use the '+' modifier to combine multiple ranges together :
1 Thru 5 + 7 Thru 9
| = 1,2,3,4,5,7,8,9
|
Finally the '-' modifier can be used to remove channels from a range :
1 Thru 9 - 6
| = 1,2,3,4,5,7,8,9
|
Complex channel ranges can be made by combining as many ranges together as required using the modifiers :
1 Thru 20 - 5 Thru 10
| = 1,2,3,4,11,12,13,14,15,16,17,18,19,20
|
1 Thru 20 - 5 Thru 10 - 15 + 30
| = 1,2,3,4,11,12,13,14,16,17,18,19,20,30
|
