No, it's wrong. See F95 13.14.71: "Result Characteristics. The result is of
type default integer.  If DIM is absent, the result is an array of rank one and
of size equal to the rank of ARRAY; otherwise, the result is of rank n-1 and
shape ..."

Note in particular the example for case (i), on the next page: "The value of
MINLOC((/4,3,6,3/)) is [2]". If DIM is absent, the result is always an array of
rank 1. Only if DIM is present, and the ARRAY is of rank 1, then MINLOC is a
scalar: MINLOC((/4,3,6,3/),1) == 2
