AR24027 Operator’s Manual
4-2
4.2 Command syntax
The command interpreter in the AR24027 is designed to accommodate both a novice as well as an
expert operator. All commands and parameters have descriptive names so that they are easily
remembered and their meaning is clear. In order to be descriptive however, those commands are
sometimes long. As the operator becomes familiar with the command language, typing the complete
words could become cumbersome. The
AR24027 command interpreter recognizes any abbreviations
to commands and parameter names, as long as they are unambiguous. If an ambiguous command is
entered, the radio will output all possible choices.
Commands have the following generic form:
command parameter=value parameter=value
Following is a brief list of syntax rules:
•
Words (for commands, parameters, or values) can be abbreviated to a point where they are
unambiguous.
•
Some commands or parameters consist of compound words separated by an hyphen. With
compound words, the hyphen is optional. Additionally each word in a compound word can be
abbreviated separately. For example, the following are all valid abbreviations for the command
“save-configuration”: “save”, “savec” s-c” “sc”.
•
The parameter and value lists are context sensitive, i.e., in order to solve ambiguities the
command interpreter only considers parameters valid for current command, or values valid for the
current parameter.
•
The arguments “parameter=value” must be entered with no blank spaces on either side of the ‘=’
sign. Those arguments (parameter/value pairs) can be listed in any order.
•
Even though parameters can be listed in any order, there is a “natural” order known by the
command interpreter. This allows the user to specify parameter values without having to type the
parameter names. For example the command
> spectrum-analysis input=a-antenna display=table
can be entered as (using abbreviation rules as well):
> spa a t
•
Using the preceding rule, for commands that have a single argument, the “parameter name” part
of the argument is always optional, i.e., you can enter:
> command value
For example the command:
> save-configuration destination=main
can be shortened to any of the following:
> save-configuration main
> save main
> save
