In some cases, logically deleted items still occupy space in the HP
ALLBASE/4GL internal name lists. If deleted items occupy a significant
amount of name list space, some of the limits listed above may be
reduced.
To recover this space, generate the entire application by selecting the
All option on the generates menu. HP ALLBASE/4GL compacts the internal
name list when it generates an entire application.
