I encounter this error message every time I call a stored procedure
with a varchar parameter.

Version: Firebird 1.5 embedded
OS: Windows XP
Interface: C/C++

Perhaps I have the syntax wrong, but what I'm sending is the
following:

EXECUTE PROCEDURE sp_myproc 1, 'my name';

And what I *always* get is:

message length error (encountered 0, expected 8)

Is this a bug in my code or firebirds???
