It is actually a valid file name, but the file is not on disk. I
presume that the OP got an error because it was in 'a' (append) mode
which requires an existing disk file. See below.
C:\junk>copy con aux.csv
fubar
^Z
1 file(s) copied.
C:\junk>copy con sux.csv
fubar
^Z
1 file(s) copied.
C:\junk>dir *ux.csv
[snip]
Directory of C:\junk
16/02/2007 01:19 AM 7 sux.csv
1 File(s) 7 bytes
Why? Who knows? We're talking CP/M, MS-DOS and Windows and you want to
know why? Probably too lazy to distinguish between 'AUX\0', 'AUX.\0'
and 'AUX.XYZ\0' ... probably stopped scanning on reaching the first
invalid character. If you're desperate to find out, dial up your
nearest RCPM and ask the sysop :-)
Cheers,
John
