Re: Type 80 query

["David Bradley" <bradley@xxxxxxxxxxxx>]

Jose,
   The error that you seeing suggests that Type80 was not included in your 
trnlib.dll. If you recompiled the dll yourself, make sure that you add 
Type80 to the project. If you are using a standard (unmodified) dll, you 
should contact your TRNSYS distributor for a new one.
regards,
   David
