When I tried to recompile the main TRNDll, I get the following error 
message with each type:
C:\Program Files\Trnsys16\SourceCode\Types\Type109.f90
f90: Error: Unrecognized keyword "arg_temp_created" for option "-check"
C:\Program Files\Trnsys16\SourceCode\Kernel\View.for
f90: Error: Unrecognized keyword "arg_temp_created" for option "-check"
C:\Program Files\Trnsys16\SourceCode\Kernel\TrnsysConstants.f90
f90: Error: Unrecognized keyword "arg_temp_created" for option "-check"
etc... for all types : it sounds like if CVF 6.1 is not able to re- 
compile/build the TRNDll, isn't it? Is there any option I should(n't) 
activate?

Moreover it's possible to create multiDll project with CVF 6.1A (See the 
screenshot attached file) and until I use the "use TRNSYSconstants" 
there wasn't pb and I was able to build the "CLIPSOLDll.dll". Since I 
have to adapt all of my previous user types to new TRNSYS 16 
programming, I have not yet attempted to run simulation that uses these 
types. So I can't say categorically that it works well about the 
multiDll structure.

Thanks
