The SOURCE >> INTENT(IN) form should have no coarray restrictions on SOURCE. The interfaces would be CO_MAX ( SOURCE, RESULT [, RESULT_IMAGE, STAT, ERRMSG ] ) and CO_MAX ( SOURCE [, RESULT_IMAGE, STAT, ERRMSG ] ) Can this work in the case that SOURCE is integer? If you CALL CO_MAX ( I, J, K ), which one is it? is it CALL CO_MAX ( SOURCE=I, RESULT=J, RESULT_IMAGE=K ) or CALL CO_MAX ( SOURCE=I, RESULT_IMAGE=J, STAT=K ) If the interfaces were CO_MAX ( SOURCE, RESULT [, ERRMSG, RESULT_IMAGE, STAT ] ) and CO_MAX ( SOURCE [, ERRMSG, RESULT_IMAGE, STAT, ERRMSG ] ) generic resolution would work, but it feels a bit weird to put ERRMSG before RESULT_IMAGE.
