Section 3: Command Descriptions

Symbols are used to denote options or alternatives in the command parameters. These symbols are used to help give a clear and complete description of the command and are not part of the command. The use of these symbols is briefly described below:

Arguments to commands are often given symbolic names which are enclosed in angle brackets (< >). For example; ª<PAGE>º is an argument to many commands. The com- mand specification for ª<PAGE>º is described as a number which specifies the page number of the display. It is important to remember to enter the argument and not its symbolic name. For example, to see the second page of the Test Results, you should en- ter:

REPORT 2 - not - REPORT <PAGE>

Optional arguments are surrounded by square brackets, for example REPORT [<PAGE>].

Again, the brackets should not be entered as part of the command.

Sometimes there are several alternatives for an argument. The alternatives are listed in the command description separated by a vertical bar () and enclosed in braces ({}). For example, when using the NET command, only one of the alternatives should be se- lected:

NET { ON OFF }

Command Input Processing

Anything in a command description that is not one of the constructs discussed above should be entered exactly as it is shown. All data entered for the command is converted to lower case unless it is enclosed in double quotes (ªº). To use a double quote character within an argument string, the double quote should be entered twice, for example: ªThis string would contain one º ªcharacter.º

The Station Manager accepts several ASCII control characters for various functions. The control characters accepted by the Station Manager are listed in the following table. All other control characters are ignored on normal command inputs. Illegal control charac- ters sent to the Station Manager result in a BEL character being sent to the terminal.

If a command line becomes too long to easily type on a single display line, the character pair ª\<RET>º can be used to continue the command on the next line on the display. The ª\º (backslash) character will not be used as a part of any argument.
