Hi Dave,

the page Message Formats
specifies that the bind message should send the following for each

    Int16 - The number of parameter format codes that follow (denoted
C below). This can be zero to indicate that there are no parameters or
that the parameters all use the default format (text); or one, in
which case the specified format code is applied to all parameters; or
it can equal the actual number of parameters.

    Int16[C] - The parameter format codes. Each must presently be zero
(text) or one (binary).

Does your understanding of the spec mean that the Int16[C] must either
be an array containg all zero's, or all ones? It reads as though these
can be mixed.

In response to
