Replaced Application	Compatible	Compatible	Not compatible [3]

[1] The application must recompile using ODBC 3.0 headers and must set ODBCVER to 0x0250. [2] The application must compile using ODBC 3.0 headers, and link with the ODBC Driver Manager. It must also set the header flag ODBC_STD. [3] This configuration can potentially fail to work because there are features in ODBC 2.x that are not in the standards, such as bookmarks. [4] This configuration can potentially fail to work because there are features in ODBC 3.0 that are not in the standards, such as bookmarks.
