Re: Dealing with very large blocks of character data

[John McKay <jmckay@xxxxxxxxxxxxxxxx>]

David,

    I have two questions before I post a  suggestion ...

    First, why do you say you are "not supper[sic] happy with the idea 
of having to deal with this data using pointers and C api's ".

    Second, what are you looking for in this data or intending to do?
