IF-Arithmetic statement • The following example transfers control to statement 50 if <strong>the</strong> real r variable THETA is less than or equal to <strong>the</strong> real variable MU. Control passes to statement 100 only if THETA is greater than MU. IF (THETA-MU) 50,50,100 • The following example transfers control to statement 400 if <strong>the</strong> value of <strong>the</strong> integer variable N is even. It transfers control to statement 200 if <strong>the</strong> value is odd. IF (N/2*2-N) N) 200,400,200 • The following statement transfers control to statement 100 <strong>for</strong> N5: IF (N-5) 100, 200, 300
IF-Logical statement • Executes one statement based on <strong>the</strong> value of a logical expression. (This statement was called a logical IF statement in FORTRAN 77) Syntax IF (expr( expr) ) stmt where: expr is a scalar logical expression (enclosed in paren<strong>the</strong>ses); stmt is an executable Fortran statement. Logical expression true statement false
