hostVarQualifier

The hostVarQualifier property contains the name of a DLISegment record variable that contains a key value used to locate a record in the database.

When you use implicit DL/I database I/O, EGL builds default SSAs for you so that you can compare the key field with a value. Typically, EGL assumes that you stored the value in the key field of the segment. In some cases, you might want the value for the key field to come from a different record, such as a basic record that is passed to the program as a parameter. In addition, to retrieve segments at a lower level of the hierarchy, EGL cannot determine which record variable to use for segments at higher levels of the hierarchy. In both of these cases, you can use hostVarQualifier to specify the name of the variable record based on the DL/I segment.
