I have a CT-Lib application that calls a stored procedure.  One of the
arguments to the stored procedure indicates whether or not to begin a
transaction.  The stored procedure, if required, will begin the
transaction but not do a commit.  This will be done later in the
application flow.  The stored procedure returns in the status code the
key piece of information that the application requires.

When the 'begin tran' is executed, an error code 266 is generated
(Transaction count after EXECUTE indicates that a COMMIT of ROLLBACK
TRANSACTION statement is missing...) with a severity level of 16.
According to Microsoft's documentation (link below), this error code is
just a warning message and can be ignored.
http://msdn2.microsoft.com/en-us/library/aa258721(SQL.80).aspx

What appears to be happening is that the return status is never
processed and passed back to my CT-Lib application (I assume) because of
the error code 266.

I've attached the excerpt from the debug log when calling the stored
procedure with the 'begin tran' mode and without.
