input into an executable command. The command string consists of
leaders, functions, delimiters, parameters and terminators.
Example Command Strings:
1. Function code.
2. Function code and parameters:
- >#58 76 [Remote Key Code 'VIEW']
- >#36 680 [Audio_Right_Frequency 6.80 MHz]
- >#59 1255 "WEST" [Longitude 125.5 WEST]
- >#30 "ESPN" [Name Channel "ESPN"]
- >#30 "GALAXY 5" [Name Satellite "GALAXY 5"]
- >#105 "CHAP. UNIT 4" [Write "CHAP. UNIT 4"
to scratch pad]
- >#107 0 [Autotune Dish Position]
Example Command Strings:
Leader:
- Pound sign "#"
Function:
- Integer 234
Parameter:
- Integer 1546
- String "ESPN" NOTE: There is a 12 character limit
on names.
