You can use double-byte character data anywhere in a CL command that descriptive text can be used.
For example, to enter the double-byte character literal ABC, enter the following characters, where SO represents the shift-out character and SI represents the shift-in character:
'SOABCSI'
Limit the length of a double-byte character text description of an object to 14 double-byte characters, plus the shift control characters, to make sure that the description is properly displayed and printed.
