File-Description Keywords
File-Description keywords may have no parameters, optional parameters, or required parameters. The syntax for keywords is as follows:
Keyword(parameter1 : parameter2)
where:
- Parameter(s) are enclosed in parentheses ( ).
Note: Do not specify parentheses if there are no parameters.
- Colons (:) are used to separate multiple parameters.
The following notational conventions are used to show which parameters
are optional and which are required:
- Braces { } indicate optional parameters or optional elements of parameters.
- An ellipsis (…) indicates that the parameter can be repeated.
- A colon (:) separates parameters and indicates that more than one may be specified. All parameters separated by a colon are required unless they are enclosed in braces.
- A vertical bar (|) indicates that only one parameter may be specified for the keyword.
- A blank separating keyword parameters indicates that one or more of the parameters may be specified.
Note: Braces, ellipses, and vertical bars are not a
part of the keyword syntax and should not be entered into your source.
If additional space is required for file-description keywords, the keyword field can be continued on subsequent lines. See File-Description Keyword Continuation Line and File Description Specification Keyword Field.
