ELSEIF logexp.
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.
