Char fields store alpha data that is either SBCS, mixed SBCS and DBCS, or DBCS-only. Chars are classified as strings.
Depending on the database type, Char may or may not treat trailing blanks as significant. If trailing blanks are not desired, a String field should be used.
...
- Working fields defined with TYPE(*CHAR) where the field length is 256 or less should operate similarly to alpha fields.
- Fields of type String or Char and length of 256 or less may be used almost anywhere that fields of type Alpha may be used.
...
- If a field is a fixed character length of 256 or less, use an Alpha field.
- If you want trailing blanks to be significant, use a String field.
