Hi,

I believe I have encountered a new (to me anyway)
datatype.  The value is 0x7B, and it looks like it
could be similar to a INTN (0x26) or FLTN (0x6d) 
from its form.

I searched the 3.6 and 3.8 Sybase TD Functional spec,
and the FreeTDS 0.64 code base and documentation.  I'd
appreciate any help.

the packet contains a "TDS_BUF_NORMAL".
The buffer contains DBRPC (0xE6), PARAMFMT (0x20)
and PARAMS (0xD7) tokens.
the PARAMFMT token has two parameter definitions
both have the datatype id is 0x7b.
There is one byte following the datatype (08), in the
PARAMFMT2 which make me think it might be similar to a
INTN, UINTN or FLTN.

The fact that the PARAMS values look like it they
might
be "smaller" than the maxiumum size:
04 18 98 00 00 = size = 04, value = 18 98 00 00
00 = size = 00 value = NULL

An editted/commented ethereal "data bytes" trace
follows.

Any ideas?

Thanks.
