The Optical Support (QOPT) file system can be accessed through the integrated file system interface. This is done using either the OS/400 file server or the integrated file system commands, user displays, and ISO stream I/O functions, and system APIs.
QOPT converts the lowercase English alphabetic characters a to z to uppercase when used in object names. Therefore, a search for object names that uses only those characters is not case-sensitive.
