An ispec transmitted with its Maint built-in attribute set to ADD (or its translated equivalent in Glb.Add) is added to the database as a new record.
In the database, an added record's Maint attribute is set to A.
ADD is the default Maint value.
To add a record with a required persistent attribute set to spaces, perform the following:
Set the attribute to a dummy value, set Maint to ADD, and transmit to create the record.
Set Maint to REC and transmit to recall the record.
Set the attribute to spaces, set Maint to CHG, and transmit to change the record.
