Inserting Records

INSERTING RECORDS

You can insert a new record in a file by entering the appropriate

values in the record fields and requesting an insert operation.

Two insert operations are available:

INSERT--to insert a single record at a time.

INSERT BOX--to insert several records at one time.

When you request an INSERT operation, you must position the

cursor within the record to be inserted. When you request an

INSERT BOX operation, you must position the cursor within the

appropriate box.

INSERT (F10)

To insert a single record into a file, request an INSERT

operation. Before you request the INSERT operation, you must

enter the appropriate values in the fields of the record to be

inserted. If you do not enter values in any of the record

fields, the application will issue the following error message:

Default record is not acceptable.

If all the information necessary to insert a record is not

available, you do not have to enter a value in each field of a

record. You can update such records later when the information

becomes available. You must, however, enter values for the

primary key field or any alternate key fields that have been

defined as requiring unique values. If you do not enter a value

in a nonkey alphanumeric or alphabetic field, the application

inserts blanks for these fields. If you do not enter a value in

a nonkey numeric field, the application inserts zeros for this

field.

If you request an INSERT operation for an entry-sequenced or

unstructured file, the application ignores any value that you

enter in a Record Number field. The application and the computer

system automatically supply the appropriate number for the

record.
