FOR Statement (Sequential Files)

The FOR statement is used for reading and updating sequential files. The FOR construct begins with a FOR and ends with an ENDFOR.

To retrieve data from a file, you must first define a CA Ideal dataview for the data. The dataview defines the record available to the application.

You can use the following FOR statements for sequential files:

• The FOR EACH, FOR FIRST, and FOR ANY constructs retrieve records. These constructs are iterative. With each iteration, they return the next record in the requested set.
• The FOR NEXT statement accesses a single record from the file.
• Records are added to the file using FOR NEW.

These statements are described in the next section. For more information about CA Ideal dataviews, see the Creating Dataviews Guide.
