condition

    A specified condition that must be met if the block is to be
    included in the assembly. The condition must be separated from
    the argument by a comma, space, or tab.

 argument(s)

    One or more symbolic arguments or expressions of the specified
    conditional test. If the argument is an expression, it cannot
    contain any undefined symbols. The assembler converts relocatable
    arguments to absolute arguments by discarding the relocatable
    portion of the expression and using only the offset from the
    beginning of the psect. Arguments must be separated by a comma.

 range

    The block of source code that is conditionally included in the
    assembly.
