SHAPE (source [,kind])

  Class:  Inquiry function - Generic

  Returns the shape of an array or scalar argument.

  The "source" must not be an assumed-size array, a disassociated
  pointer, or an allocatable array that is not allocated.  The "kind"
  must be a scalar integer initialization expression.

  The result is a rank-one integer array whose size is equal to the
  rank of "source".  If "kind" is present, the kind parameter of the
  result is that specified by "kind"; otherwise, the kind parameter
  of the result is that of default integer.  If the processor cannot
  represent the result value in the kind of the result, the result is
  undefined.

  The value of the result is the shape of "source".

  The setting of compiler options that specify integer size can
  affect the result of this function.

  Examples:

  SHAPE (2) has the value of a rank-one array of size zero.

  If B is declared as B(2:4, -3:1), then SHAPE (B) has the value (3,
  5).
