Keyword Instance Specification

When a specific instance is required, it can be specified using one of the following

keywords, or by using the asterisk (*) symbol:

• The begin keyword: If you want to specify an attribute instance located at the

beginning of the list, use the begin keyword. This keyword is supported only by

the insert command, on the left side of the = operator. Following is an example

of a correctly formatted keyword instance specification:

insert Reply-Message[begin] = "This is first"

For more information on the insert command, see “The insert Command”

(page 409).

Using the begin keyword with other commands results in an

invalid-instance-specification load-time error.

• The last keyword: If you want to specify the last instance of an attribute , use

the last keyword. Following is an example of a correctly formatted keyword

instance specification:

Reply-Message[last]

NOTE: This is the default value if no keyword is specified.

• The asterisk keyword: If you want to specify all instances of an attribute, use the

asterisk (*) symbol. The following example specifies all instances of the

Reply-Message attribute:

Reply-Message[*]

This format is supported only by the delete command, the log command, and

the count() attribute function. Using this format in unsupported contexts results

in an invalid-instance-specification load-time error. For more information on the

delete and log action commands, see “The delete Command” (page 408) and

“The log Command” (page 412). For more information on the count() attribute

function, see “The count Attribute Function” (page 418).
