The /ELSE compiler directive is used to unconditionally select source lines to be read following a failed /IF or /ELSEIF test.
See Compiler Directives for information on
the columns available for directives.
/ELSE can be specified within
any free-form statement other than a free-form calculation statement.
See Conditional Directives Within a Free-Form Statement.
The remainder of the line containing /ELSE must be blank.
If the previous /IF or /ELSEIF was not satisfied, source lines are selected until the next /ENDIF.
If the previous /IF or /ELSEIF was satisfied, source lines are excluded until the next /ENDIF.
