MIN is doing exactly what it is supposed to do.

From the online help:

"The MIN function returns the value of the smallest element of Array.
The type of the result is the same as that of Array.

Syntax
Result = MIN( Array [, Min_Subscript] [, /ABSOLUTE] [,
DIMENSION=value] [, MAX=variable] [, /NAN] [,
SUBSCRIPT_MAX=variable])

Return Value: Returns the smallest array element value.

Arguments
Array: The array to be searched.
Min_Subscript: A named variable that, if supplied, is converted to a
long integer containing the one-dimensional subscript of the minimum
element. Otherwise, the system variable !C is set to the one-
dimensional subscript of the minimum element."

Cheers,
Liam.
