The "if" statement allows for Fortran-77 style logical or block if statements. A logical "if" statement must not end with the word "then".

if (mod(i,2).eq.1) then print "$i is an odd number." else if (def(’x’) .and. exist(’y’)) then print "x is defined, and y exists." else if (s.eq.’ ’) then print "The variable s is blank." end if
