attempting to compile using CVB v6.6 project file

Hello, 

I am new to Visual Studio, and a novice user for CVB. However, I have well documented code that reportedly compiles fine on compaq visual basic v6.6. I have successfully installed Visual Studio 2013 (and 2015) as well as the necessary Intel Parallel Studio XE 2016. When I try to compile the code, i get this error: 

warning MSB8018: No outputs specified for item "myCode.f90". Its custom build command will be skipped.

Any advice would be appreciated. Thank you
