Character processing on i5/OS™ is controlled by these coding rules
and guidelines that ensure consistent processing of character data.
The rules and guidelines cover tasks such as:
- Converting character data to all uppercase or to all lowercase data
- Folding data (substituting printable or displayable characters for those
that cannot be printed or displayed on a particular device)
- Processing character data strings
- Classifying characters
- Naming objects
- Determining data, file, and field lengths
