WebThere are three Fortran functions that can be used to retrieve the extent and the size of an array: SIZE (x) takes an array and returns the number of elements in x. LBOUND (x) takes an array and returns the lower bound of x () 's extent. UPPER (x) takes an array and returns the upper bound of x () 's extent. WebHowever, I will do it when I feel a bit braver!

WebFortran 90 allows arrays to be created on-the-fly; these are known as deferred-shapearrays and use dynamic heap storage (this means memory can be grabbed, used and then put back at any point in the program).
