IF1              Assemble If Pass 1                            MASM Directive
 
  IF1
  statements
  [ELSE
  statements]
  ENDIF
 
    Initiates a conditional block, causing assembly of the statements up
    to the optional ELSE directive, provided the current assembly pass is
    Pass 1.
 
       Notes:     IF1 tests only for the current assembly pass, and
                  therefore takes no expression argument.
