[TRNSYS-users] Call external file through special cards with C++

[xingbin lin]

Dear Werner:
Thank you for your help so much,Your solution is that to provide a dll which
is programmed by fortran,then I can build a C++ class to read the file
content according to the logical unit number,this is very smart.
However,what I just want to get the file path which is assigned in the
specail cards in the new type.That is to say,I would like to get the path of
the file in my type,not the content.
Can you provide me more advices? Thanks a lot!
