Command and syntax reference

This section provides the information about available commands in File-AID/MVS.

Notation Rules

This section uses the following notation rules:

• Screen displays are printed as shown by the product, in upper and lowercase characters.
• Boldface type indicates data that you are to enter on the screen.
• Railroad logic syntax diagrams are used to define primary and line command syntax. See "Syntax Diagram Notation Rules ".

• The names of special function keys are defined as follows:

  Key	Description
  Enter	The keyboard Enter key. When pressed, information is transmitted to File-AID.
  HELP	PF key used to display tutorial information or a longer error message. Usually defined as PF1.
  END	PF key used to end the current process. Usually defined as PF3.
  RETURN	PF key used to end the current process and return to the primary menu. Usually defined as PF4.
  RFIND	PF key used to repeat a find condition already entered. Usually defined as PF5.
  UP	PF key used to scroll up the display. Usually defined as PF7.
  DOWN	PF key used to scroll down the display. Usually defined as PF8.

Syntax Diagram Notation Rules

The syntax for File-AID commands is described in diagrams that help you visualize parameter use. The following example shows a command and a parameter:

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.
• All variables are user-specified values and are printed in lowercase italics. For example, dataset-name indicates you are to substitute a value.

Read the diagrams from left to right and from top to bottom. These symbols help you follow the path of the syntax:

Required parameters appear on the horizontal line (the main path):

Optional parameters appear below the main path. Default parameters that appear above the main path are optional; including or excluding them in the command has the same effect on the execution.

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 one of the parameters in a stack is the default, it appears above the main path:

An arrow returning to the left indicates a repeatable item.
