Criteria for writing DLLs

You can write DLLs in any language, provided the language has the following capabilities:

      64-bit floating point array parameters

      Pointers to 16-bit integers

      _stdcall calling conventions (default for Microsoft Fortran and Delphi Pascal)

Example DLLs written in C, Fortran, and Pascal reside in subdirectories under Embed-install-directory\VSDK.
