Returns the lower bounds of an array, or a single lower bound along the
result = lbound(array [, dim [, kind]])
array- Shall be an array, of any type.
dim- (Optional) Shall be a scalar
kind- (Optional) An
integerinitialization expression indicating the kind parameter of the result.
The return value is of type
integer and of kind
kind is absent, the return value is of default integer kind. If
dim is absent, the result is an array of the lower bounds of
dim is present, the result is a scalar corresponding to the lower bound of the array along that dimension. If
array is an expression rather than a whole array or array structure component, or if it has a zero extent along the relevant dimension, the lower bound is taken to be 1.
