Error: Dummy argument 'value' with INTENT(IN) in variable definition context (assignment) at (1) ! but do not even though VALUE is INTENT(IN) and changed the value There is a programmer error in the example program. The variable VALUE has been declared to be INTENT(IN) but the routine assigns a value to the variable. This should be caught at compile time.
