An NCL verb is a keyword that denotes a specific action, such as creating a variable or
generating a message. Some verbs require additional parameters known as operands.
The CONTROL verb is a singular case in which the operands may modify NCL
execution characteristics.
This section describes the verbs that you can use in NCL. The full description of each
verb contains:
A brief overview of what the verb does.
A diagram showing the syntax of the verb.
Descriptions of each operand in the verb.
Considerations that affect the usage of the verb.
A list of related verbs, or other NCL statements.
At least one example of the use of the statement. Null strings are indicated in
examples by two single quote characters together (‘‘). The purpose of the
examples is to show the correct method of coding the verb. Some examples
include a complete NCL procedure.
Following “Summary of Verbs,” next, is a description of frequently occurring
operands common to many verbs: ARGS, PARSE, RANGE, SEGMENT, and VARS.
For help in understanding syntax notation, see “Notation Conventions” at the
beginning of this manual.
