STORAGE_ERROR Exception

STORAGE_ERROR Exception

[Matthew Givens]

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.
