I didn't get the usual confirmation that the following message was distributed to the mailing list. Perhaps it was rejected because the "To" address was duplicated in the "cc". If it was distributed , please excuse the duplicate posting. Thanks.

My intention is for the package to run on free systems using only free software. In practice, this means first and foremost GNU/Linux, to be followed, if possible, by FreeBSD. All dependencies on Microsoft products will be removed _unless_ the same functionality is available for free systems. This is in accordance with the GNU Coding Standards, as well as my own wishes. I would be perfectly happy for the package to run on Microsoft systems, but this is a secondary consideration. > Much of the code is > written in C++ (++), but don't know how portable that is.

In the earlier parts, namely `ATest', which accesses OAI servers, I used more features specific to Visual Studio and Visual C++. In `ZTest', which accesses data from Z39.50 servers using the YAZ package, tried to avoid using these features and used standard C++ and the Standard Template Library as much as possible. The most recent program, `scantest', which implements the beginnings of what I call a "generic query language" uses GCC (the GNU Compiler Collection) and runs under GNU/Linux. Standard C++ is quite portable, features from the Microsoft libraries are virtually non-portable and must be replaced. Threads may be a problem. I plan to use Posix threads, which are supported on all UNIX-like systems (to the best of my knowledge). I no longer have access to a Microsoft system and will not support the Microsoft versions. I plan to build the package up around `scantest', which I will be renaming. I will probably call it the "GNU Generic Query Language Interpreter". At some later date, I may port the projected GNU/Linux version to Windows (or even MS-DOS). However, I would prefer to do this using GCC and cross-compilation rather than Visual Studio. I don't plan to use Microsoft SQL Server anymore. The SQL code I've written seems to be reasonably portable. I don't think it will be difficult to adapt it to other database software using other versions of SQL. Of course, if I do find a library or other institution interested in supporting this work, that institution would have a say in how I proceed, as long as the requirements of the GNU Project are satisfied. Thank you for your interest. Laurence Finston
