In the following examples of syntax codes, the special characters are explained:
The characters in square brackets [ ] represents a command string, either upper or lower case command
characters accepted. All characters must follow each other in the string with no spaces or other charac-
ters.
The characters within wavy brackets { } contain choices for the appropriate command.
The characters within the symbols < > are the common abbreviations for the one digit ASCII control
codes which they represent, (e.g. <CR> represents carriage return).
When entering more than one command in the same data string, they must be separated by a comma.
All command strings must be followed by the terminator character (carriage return <CR>, also known
as ENTER).
When a lower case character is present in an example it represents an option.
