argument-1
Must be class alphabetic or alphanumeric, and must be at least one character in length.
IBM Extension

Argument-1 can be DBCS or national.

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.
