VFP 9 FREAD/FWRITE Undocumented Limit

While doing a low-level routine for copying data between files for showing advance, I've descovered something interesting:

Documentation says that FREAD support 65536 bytes (64 KiB) max.length, but the limit in VFP 9 is really 16777184 bytes (16 MiB), iow, 256 more times!

And another interesting thing is that this limit is the same of the max.size of a string variable:

Maximum # of characters per character string or memory variable. 16,777,184

A "little" detail that the FoxTeam forgot to document.

This should be added to VFPx FoxHelp File.

Best Regards!
