### .CREF/.XCREF (Control Symbol Cross Referencing)

The output of the cross-reference information is controlled by these directives. The default condition is the .CREF directive. When the assembler finds a .XCREF directive, cross-reference information results in no output until the assembler finds

Note: The assembler does not produce cross-referencing information. These directives are provided for source file compatibility with other assemblers .

Syntax

    . CREF
        or
    . XCREF   [ [ operand   [ , . . . ] ]

Remarks

The .XCREF directive can have an optional operand consisting of a list of one or more variable names suppressed in the cross-reference listing.
