.Sh DESCRIPTION
.Pp
.Nm
is very similar to the 
.Ql isql
utility programs distributed by Sybase and Microsoft. Like them, 
.Nm
uses the command 
.Ql go
on a line by itself as a separator between batches.

.Sh NOTES
.Nm
is a filter; it reads from standard input, writes to standard output,
and writes errors to standard error. The
.Fl i Ns ,
.FL o Ns ,
and
.Fl e
options override these defaults.
.Pp
.Nm
uses the DB-Library API provided by FreeTDS. It was first implemented using
Sybase's own library and continues to work with it. Before (and after) modifying
it, it would be well to test it with Sybase's library to assure compatibility
between it and FreeTDS.
EXIT STATUS
.Pp
.Nm
exits 0 on success, and >0 if the server cannot process the query.
.Pp
.Nm
will report any errors returned by the server, but will continue
processing. In a production environment, this behavior may be insufficiently
stringent. To make it extremely intolerant of errors, change the message and
error handlers to call exit(3).
