HP Transact Documentation Update Notice

Using Dictionary Definitions with Data Item Relations 

You must use caution when using data dictionary definitions of
parent/child relations, compound/sub-item relations, and aliases.  You
must specifically define an alias relation in the DEFINE(ITEM) statement
of your Transact program; any alias relations defined in a data
dictionary are ignored by Transact.  The Transact processor recognizes
parent/child and compound/sub-item relations defined in a data
dictionary, but you can only reserve space in the list register for the
parent or compound item.  (For details, see the DEFINE(ITEM) discussion
in Chapter 8, and the sections "Parent Items and Child Items," "Compound
Items," and "Alias Items" in this chapter.)
