condition

    One of the legal condition tests defined for conditional assembly
    blocks (see the description of .IF). The condition must be
    separated from the arguments by a comma, space, or tab. If the
    first argument can be a blank, the condition must be separated
    from the arguments with a comma.

 argument(s)

    An expression or symbolic argument associated with the immediate
    conditional assembly block directive. 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. The arguments
    must be separated from the statement by a comma.

 statement

    The statement to be assembled if the condition is satisfied.
