QUALIFIED
The QUALIFIED keyword specifies that the subfields of a data structure will be
accessed by specifying the data structure name followed by a period and the
subfield name. The data structure must have a name.
The subfields can have any valid name, even if the name has been used elsewhere
in the program. This is illustrated in the following example:
* In this example, FILE1 and FILE2 are the names of files. FILE1 and FILE2 are
* also subfields of qualified data structure FILESTATUS. This is valid,
* because the subfields FILE1 and FILE2 must be qualified by the data structure
* name: FILESTATUS.FILE1 and FILESTATUS.FILE2.
Ffile1 if e disk
Ffile2 if e disk
D fileStatus ds qualified
D file1 N
D file2 N
C open(e) file1
C eval fileStatus.file1 = %error
