Okay, I have a problem working with Ada under SunOS.
I'm retrieving rows of data from a database, formatting a string of data
suitable for display, storing the string in one giant string of rows
(separated by LF's), and displaying the rows 50 at a time in the listbox
after all rows have been retrieved.
The problem come in when handing large sets of data. The program dies
with a STORAGE_ERROR on the record #1600, every time. It's dying as I
try to allocate the new row. Now, all I can think of is that I'm
mismanaging memory somewhere, but I can't find it.
Is there a way to determine how much memory is available for allocation?
I could do it easily in DOS or MS-Windows, but don't know how to do it
here. Having this would make tracking down the errors just a tad easier.
And, if anyone has any other thoughts as to why this is happening, please
don't hesitate to offer them.
Thanks in advance.

I believe there is a limitation in sunada on the maximum data structure
size. I think it's around 8 megabytes. I ran into this problem a few
years ago using sunada. Check the manual that came with it for these
constraints. Appendix F I think. I was able to work around it without to
much trouble. Good luck.
