Nonstop Database, HiRDB Version 9 UAP Development Guide
The character set descriptor area is used for setting character set names for input and output variables that are determined dynamically during UAP execution, and for reporting them to the system with the OPEN, FETCH, and EXECUTE statements. During dynamic execution, the character set descriptor area can also be used to receive a character set name for a ? parameter or an item retrieved by a preprocessed SQL statement.
For details about the UAP coding languages that use the character set descriptor area, see 3.2 Overview of UAPs.
