There are the tools needed to build a T16 dll :
uncompress the ZIPfile into a directory, which contains:
- The WINDOWS.H file, RC.EXE, RCPP.EXE from Visual C++ 1.x
- RESOURCE.H, VER_INFO.RCV fro WinImage translation kit
- the .RC file translated

To build the .t16, you'll do:
copy /b dllres16.dll winimarc.dll
rc -r WINIMARC.RC
rc  WINIMARC.Res WINIMARC.dll
copy /b winimarc.dll winimarc.t16

Note : for building a Help file modified with WinWord, you need Help
