I'm new in Fortran and using Visual Fortran Composer XE 2013 on Windows 7.
In side of main program I'm calling a subroutine by using: CALL CCOEFF(DL, DD, DDD) and I'm getting these errors:
Error 1 error #7976: An allocatable dummy argument may only be argument associated with an allocatable actual argument. [DDD]
Error 2 error #8055: The procedure has a dummy argument that has the ALLOCATABLE, ASYNCHRONOUS, OPTIONAL, POINTER, TARGET, VALUE or VOLATILE attribute. Required explicit interface is missing from original source. [DDD]
By changing DDD in main program to an Allocatable argument (which related to error 1) I'm getting just the error 2 which I have no idea about it.
It would be very kind of you to help me figure it out.
Thanks in advance and Best Regards,
