ELSEIF



ELSEIF

     Provides an alternate execution sequence within an IF
     statement.

SYNTAX

     ELSEIF expression[THEN]


PARAMETERS

expression          Logical expression, consisting of operands and
                    relational operators. The THEN keyword is optional.
                    It may be used or omitted and has no effect on the
                    results.  Refer to the IF command for a list of the
                    operators that may be incorporated into an
                    expression.



OPERATION

     The ELSEIF command is used only in conjunction with the IF
     command and provides a means to avoid nested IFs.  Any number
     of ELSEIFs may follow an IF command.  In contrast, only one
     ELSE may follow an IF or ELSEIF.  For more information, refer
     to the ELSE and IF commands.

        FUNCTIONS at the HELP prompt.  Or, you may enter an
        individual function name for more specific information.

     o  To see a list of FINFO options, type FINFO at the HELP prompt.

     o  To see a list of predefined MPE/iX variables, type VARIABLES
        at the HELP prompt.  Or, you may enter an individual variable
        name for more specific information.

     This command may be issued from a session, job, program, or in
     BREAK.  Pressing [Break] terminates the INPUT() function.

EXAMPLE(S)

     The following example illustrates ELSE with the IF command

     IF EXPN1 THEN
        ...
     ELSE
        IF EXPN2 THEN
           ...
        ELSE
           IF EXPN3 THEN
              ...
           ELSE
              ...
           ENDIF
        ENDIF
     ENDIF

     The same result can be accomplished more economically by
     using ELSEIF with the IF command

     IF EXPN1 THEN
        ...
          ELSEIF EXPN2 THEN
          ...
          ELSEIF EXPN3 THEN
          ...
          ELSE
          ...
     ENDIF
