Case-sensitivity in the QSYS.LIB file system
In general, the QSYS.LIB file system does not distinguish between uppercase and lowercase characters in the names of objects.
A search for object names achieves the same result regardless of whether characters in the names are uppercase or lowercase.
However, if a name is enclosed in quotation marks, the case of each character in the name is preserved. A search involving quoted names, therefore, is sensitive to the case of the characters in the quoted name.
