Cannot open enough files

Cannot open enough files

[Fabrizio Castrotorres]

Is there a File limit established by config.nt fot gnat 10.0
under windows NT. I get an error that I cannot create a file. This happens
after I have opened a lot of files, less than 100. I exception I get is
NAME_ERROR event though I already created files with similar names, I print
the name out and is a legal ascii string. I have even increaded the "files"
attribute in config.nt. Any help would be greatly apreciated.

please reply to
fcastrot@acdnj.itt.com

Thank You.

This is a problem which has been addressed in the GNAT mailing list called
GNAT chat, to which you can subscribe by sending a message with the subject

The consensus is that this *is* a known limitation of GNAT 3.10p for NT but
which is due to a limitation in the underlying MS runtime. It is apparently
fixed in the latest commercial release of GNAT, but not (yet) in the public
release.

Try GNAT for DOS: with FILES=255 in config.sys, GNAT 3.07 and 3.10 can
open 248 files - at least under DR-DOS, MS-DOS, Windows 95.
