Accessing more than 64k in a LONG RAW

I'm wishing to use a long raw to store some data, but according to the Pro*Ada guide, the maximum amount of raw data I can hold in a variable is 64k. How can I access more than this? (Long raw is supposed to hold up to 2Gb, so there's got to be some way to access it....)

If it helps, I'm using Oracle 7.2 and Pro*Ada 1.7 on a Sun SPARC running Solaris.

Any help would be greatly appreciated!
(Please respond with e-mail - I don't get to my news server very often.)
