RE: GDBM files

Your problem is that the default is for the tie DB_File call to create a new file. The following excerpt is taken from the DB_File docs:

tie %A, "DB_File", "filename" ;
is equivalent to:
tie %A, "DB_File", "filename", O_CREAT|O_RDWR, 0666, $DB_HASH ;

Try it without the implied O_CREAT argument:

tie (%HASH, "DB_File", $filename, O_RDWR) or die "Can't open $filename
+: $!\n";

Thanks for the info. Now it gives the following very helpful error message: `Can't open trans.gdbm:` [download] What's that? Is $! undef all of a sudden? Sigh. I'll keep pluggin' away.	[reply] [d/l]

Nah, O_CREAT is just "Create the file if it doesn't exist." I'd say the real problem is that DB_File doesn't support GDBM files. :) Try GDBM_File instead. It's part of the default perl5 distribution (though it won't be installed unless you have the appropriate GDBM libraries and include files.) -Matt	[reply]
