Unable to get past problem in code

All,

I have been trying to compile a code handed over to me. I am using Visual Studio with the Intel Fortran 10.1.011 compiler. I created the project and included all the necessary files and everything else that was required and was able to get the program to build with no errors. When I go to compile it, the program pops up a console window and seems to be waiting for some input for ever. I have tried many things and nothing seems to be working. I am providing the part of the code where it seems to be having this issue below.

c    If CODE is being used "Standalone", read from unit 5 redirected input.

c    If CODE is being called from AutoTune, the description file name is 

c    passed in.

    if (IsMain) then

        lun_description = 5

        OPEN(   UNIT=lun_description,

     1            STATUS='OLD',

     1            READONLY,

     1            CARRIAGECONTROL='LIST')

    else

        OPEN(   UNIT=lun_description,

     1            FILE=DescFileName,

     1            STATUS='OLD',

     1            READONLY,

     1            CARRIAGECONTROL='LIST')

    endif

      READ(UNIT=lun_description, ERR=915, NML=OPER_INFO)

    rewind(lun_description)

 

Note that I have checked that in the project properties, I have provided the path to the location where the project file exists. Also, the input file that this program is supposed to read is provided in that folder. I have also provided the name of this file under "command line arguments". It almost seems like this "unit=5" is open somewhere and I am not able to find it nor understand what exactly FORTRAN is looking for. Can any of you gurus out there point me in the right direction?

Thanks

Max
