IF E THEN E1 ELSE E2 ENDIF
IF E THEN E1
ELSIF E' THEN E1' ... ELSE E2 ENDIF
The expression IF E THEN E1 ELSE E2 ENDIF consists of a value E of type BOOLEAN and of two values E1 and E2 of same type which is also the type of the conditional expression. The value of the expression is E1, if E is TRUE, and E2, otherwise.
The more general form
IF E THEN E1
ELSIF E' THEN E1'
ELSIF E" THEN E1"
...
ELSE E2
ENDIF
is a syntactic short cut for
IF E THEN E1
ElSE IF E' THEN E1'
ELSE IF E" THEN E1"
...
ELSE E2
ENDIF ... ENDIF ENDIF
