Gentlemen, thanks for all of the replies. I probably won't get back to
this project until next week, but I wanted to acknowledge your
contributions. It's apparent I still have much to learn about this type of
stuff.
The biggest concern was, if I didn't use varchar, I'd always be passing
16MB of data to Qc3CalculateHash. 95% of the time, the length of the data
to be hashed won't exceed 100KB, but those outliers kill ya, so I
accommodate the max. Do I understand correctly that, by specifying
%addr(DataToHash:*DATA), that no data is being copied, but simply the
address of that data is passed to Qc3CalculateHash? If that's the case, I
wouldn't need to worry about defining DataToHash as varchar; just define it
as char. Do I have that right?
