By all means correct me if I'm wrong, but I thought that passing an 
array directly (rather than as an instance of a user-defined type) was 
illegal? I'm afraid I couldn't find a reference in ISO 7185, but my 
text claims that "to use subrange type declarations with formal 
parameters in a function or procedure header, we must globally define 
the subrange type using a TYPE definition", and, later, "to solve this 
problem we *must* globally define the type of the array, since the 
arrays will be used as actual arguments to the procedure". I could be 
misinterpreting this, of course, but it does seem to suggest that "raw" 
arrays cannot be parameters.
