VisualAge Generator: A record can specify another record as the alternate specification (altspec) record. For example, if RecordA specifies an altspec of RecordB, then RecordB provides the structure for RecordA. For SQL records, RecordB also provides the list of tables and keys for RecordA. If RecordA specifies a key item, that item is merged with the keys from RecordB when determining the default selection condition.
EGL: A record can embed another record to obtain the record structure. Only the record structure is included. Each SQL record must explicitly state its entire set of tables and keys.
Associated part needed for migration: If RecordA is an SQL
record, you need the record specified as the altspec record (RecordB).
