- You may want to contact Crystal Software on (906) 822 7994. They
- sell libraries which implement almost all the Lattice-specific
- non-standard library functions, and most of the add-ons, for other
- compilers such as Microsoft, Borland and Watcom.
-
- You should also contact Copia International on (708) 682 8898. They
- have an ISAM package called AccSys which was developed by the same
- people that wrote the Lattice package, and is much better than it.
- The call structure is similar, but not quite call-compatible.
-
- Both Crystal and Copia are headed by former Lattice people.
-
- Finally, Lattice themselves have always sold their file package for
- Microsoft as well as Lattice C, and as far as I know this is still
- available from them. You'll find it has not been upgraded for
- several years and, unlike the Crystal and Copia packages, may not
- work well with Windows.
