Commands and syntax reference
The commands are presented in alphabetical order with syntax diagrams. Command abbreviations are in the command heading enclosed in parentheses.
Notation rules
This space uses the following notation rules:
- Screen, field, and column names appear with initial caps. For example:
- ...on the Extract specification screen
- ...in the Region Type field
- ...in the Line Cmd column
- Primary command names appear in all uppercase. For example, Enter the FIELD command to...
Reading the syntax diagrams
Syntax diagrams define primary command syntax.
A parameter is either a keyword or a variable.
All KEYWORDs are shown in uppercase characters and must be spelled exactly as shown. You cannot substitute another value. If any part of a KEYWORD is shown in lowercase characters, that part is optional.
Variables are user-specified values and are printed in lowercase italics. For example, dataset-name indicates you are to substitute a value.
The syntax for commands is described in diagrams that help you visualize parameter use. The following example shows a command and a parameter:
Read the diagrams from left to right and from top to bottom. These symbols help you follow the path of the syntax:
| indicates the beginning of a statement. |
| indicates the statement is continued on the next line. |
| indicates the statement is continued from the previous line. |
| indicates the end of a statement. |
Required parameters appear on the horizontal line (the main path). Optional parameters appear below the main path. Default parameters appear above the main path and are optional. The command executes the same regardless of whether the default parameter is included.
Vertically stacked parameters are mutually exclusive. If you must choose a parameter, one item of the stack appears on the main path. If the parameters are optional, the entire stack appears below the main path. If a parameter in a stack is the default, it appears above the main path.
If the same parameters are used with several commands, their syntax may be documented in a separate diagram. In the command syntax, these common parameters are indicated with separators before and after the parameter name.
An arrow returning to the left indicates a repeatable item. If the arrow contains a comma, separate the repeated items with a comma.
