The first step in creating an unmodeled sequential file dataview is identifying the dataview. To identify the dataview, you must first enter the CREATE DATAVIEW command, and then fill in the Dataview Identification screen. Once you name the dataview either in the CREATE DATAVIEW command or on the Identification fill‑in, an entry for the dataview definition is stored in the dictionary facility. After the dataview is identified, it becomes the current definition.
The CREATE DATAVIEW command presents a blank dataview identification fill‑in. This fill‑in establishes the dataview name and provides identification information for the dataview that is kept in the dictionary. CREATE DATAVIEW creates version one in test status. You can modify, duplicate, print, delete, and mark this version to production status, just like any other CA Ideal entity.
Use the CREATE DATAVIEW command to display the dataview identification fill‑in for a new dataview. To display the Identification fill‑in for an existing dataview:
The dataview identification fill‑in shown below enters descriptive information about the sequential file dataview, either when the dataview definition is initially created or when it is subsequently modified.

The components of the dataview identification fill‑in are as follows:
Specifies the name, one‑ to 18‑character, assigned to the sequential file dataview definition. CA Ideal initializes the name to the name entered in the CREATE command or prompter, if a name was supplied.
Type of file being defined: VSAM for a VSAM file, SEQ for a sequential file. Once the access method is entered and accepted, you cannot modify this value.
Specifies the type of operating system under which the dataview is accessed. The default value for this field is the current system.
Initial creation date of the dataview definition and the user ID of the creator. This information appears only after the name is entered and accepted.
Identifies the Date, time, and user ID of the last edit access. This is blank until an EDIT DATAVIEW command accesses this definition. This information appears only after the dataview name is entered and accepted.
Identifies the Date, time, and user ID of the last catalog.
Specifies the brief description of the dataview definition the user entered.
Specifies the full description of the dataview definition, up to five lines long.
