UPPER-CASE
The UPPER-CASE function returns a character string that is the same length as the argument specified, with each lowercase letter replaced by the corresponding uppercase letter.
The function type depends on the argument types, as follows:
| Argument Type | Function Type |
|---|---|
| Alphabetic | Alphanumeric |
| Alphanumeric | Alphanumeric |
| DBCS1 | DBCS1 |

- argument-1
- Must be class alphabetic or alphanumeric, and must be at least
one character in length. IBM Extension
IBM Extension Argument-1 can be DBCS or national. End of IBM Extension
End of IBM Extension
The same character string as argument-1 is returned, except that each lowercase letter is replaced by the corresponding uppercase letter. A program collating sequence or code page does not affect the returned value.
IBM Extension If argument-1 is DBCS, the DBCS value is not affected. If argument-1 is a mixed literal, only the single byte portions of the literal are affected. End of IBM Extension
The character string returned has the same length as argument-1.
