DIM intrinsic function

Standard: F77 F90 F95 F2003 F2008 Example program

---

＜Syntax＞

DIM ( X, Y )

X : Integer or Real;
Y : Same type and kind as X, conformable with X; the NAG Fortran Compiler also permits Y to have a different kind (this is non-standard);

Result : Same type as X, with kind the same as the kind of X+Y.

＜Semantics＞

The result is the maximum of X−Y and zero.

Like many intrinsic functions, this is elemental; if either (or both) of X and Y is an array, the result will be an array with that shape, with the value being computed elementwise.
