symbol cross-reference information for only those symbols that
are referred to is generated as part of the assembler listing. Any
symbols that are defined, but not referred to, are not included in
the cross-reference listing.
FULL
symbol cross-reference information for all symbols used in the
assembly is generated as part of the assembler listing. This includes
symbols that are defined, but never referred to.
UNREFS
the assembler produces the Unreferenced Symbols Defined in
CSECTs section of the assembler listing. The symbols are listed
in symbol name order. UNREFS can be specified with the SHORT suboption
to produce a cross-reference list of referenced symbols. The UNREFS
suboption can not be specified with the FULL suboption.
NO
symbol cross-reference information is not generated as part of
the assembler listing.
