ELSE             Assemble If Condition Not Met                 MASM Directive

  IF conditional
  statements
  [ELSE
  statements]
  ENDIF

    Causes the assembler to generate code for one or more statements if
    the IF condition is not met.  The statements between the IF directive
    and the ELSE directive are processed when the IF condition is
    satisfied.  If, on the other hand, the IF condition is not satisfied,
    the statements between the ELSE directive and the ENDIF directive are
    processed.

       Notes:     A nested ELSE directive is matched with the nearest IF
                  directive that does not have an ELSE directive.
