Hi Chis, yes that was my initial though too, but ... how do you distinguish the ',' separators from any comma's within any field contents before replacing them?

As for 32 kb chunks, can't you just use a FileReadEx() and manipulate the blob? (of course there's still a limit).

Yes, you would need to have a little smarts in the utility app to replace only the commas where appropriate.

That's a good question about the FileReadEX() command. That would work well on small files but blow the PB App out of the water memory wise on very large files. Whereas the FileRead() & FileWrite() commands will allow you to process super large files in 32K chunks. I wrote such a utility for a PB customer to process Bell Canada files > 2G (even 10G+) and this technique worked flawlessly. ;-)

Yes, it truly is a shame that there's no guarantee that even if you have enough free memory on the PC, powerbuilder will be (or not) able to address it.

As I've understood, PB is pretty random in assigning "it's own heap", so indeed, when having files bigger than maybe 200 or 400mB things start blowing up. Once again, I think a C# DLL might help out enormeously on doing stuff like this (without the problem of the memory allocation).

32 KB blocks might be solid, but it's just sooooo much slower !
