ASSEMBLER DIRECTIVES->Other Assembler Directives->XREF

XREF    Reference external symbols

The XREF directive lists the symbols that are used in the current module but which are defined in other modules.

Format:

XREF[.S]    [<segment name>:](<symbol list>),[<segment name>:](<symbol list>),....


where <segment name> is the name of the section defined in the SECTION directive. (At present the linker does not use this information).

and <symbol list> is a comma separated list of symbol names.

The optional .S indicates that the symbol value is less than 0FFH (although the assembler does not currently make use of this information).

Examples:

    XREF    MYCODE:routine1,routine2,routine3,MYDATA:table1

    XREF    routine1,routine2,routine3,table1

where	<segment name> is the name of the section defined in the SECTION directive. (At present the linker does not use this information).
and	<symbol list> is a comma separated list of symbol names.
