Maybe we can start with babysteps.

The prototype for SQLSetConnectAttr is:
SQLRETURN SQLSetConnectAttr(
SQLHDBC ConnectionHandle,
SQLINTEGER Attribute,
SQLPOINTER ValuePtr,
SQLINTEGER StringLength);

So in VFP, I'm doing:
DECLARE INTEGER SQLSetConnectAttr IN odbc32 INTEGER, INTEGER, LONG, INTEGER

Does this look OK to everyone?
