Within a processing block enclosed by "IF ... ENDIF", this
statement indicates the processing to be executed if the logical
expressions specified by IF
and the preceding ELSEIFs are false, but the logical expression in
this ELSEIF processing block is true.
Between the IF and ENDIF statements, there may be any number of ELSEIFs. These may be followed, optionally, by an ELSE statement, but this is executed only if none of the logical expressions under IF or ELSEIF is true.
DATA RESULT TYPE I. ... IF RESULT < 0. WRITE / 'Result less than zero'. ELSEIF RESULT = 0. WRITE / 'Result equal zero'. ELSE. WRITE / 'Result greater than zero'. ENDIF.
Depending on the value of RESULT, the three different texts are output.
