{XREF | XREF=NO | NOXREF}
When the XREF option is specified, the binder produces a cross-reference table of the program module in the SYSPRINT data set. In the case of an empty module, no program module map will be generated. If you also need a module map, you must request one using the MAP option. Figure 1 contains an example of a cross reference table.
When a bind specifying the XREF option fails resulting in a not-executable (NX) module, a cross-reference table will be included in the binder listing.
XREF=NO is the default value and can also be specified with the keyword NOXREF.
