Unable to get past problem in code

Unable to get past problem in code

Unable to get past problem in code


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,
OPEN( UNIT=lun_description,
1 FILE=DescFileName,

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

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?



RE: Unable to get past problem in code

Like the note says, I would speculate that you are expected to provide input via unit 5 since you have launched the program directly...as opposed to having been launched via another application.

Unit 5 in Fortran is nothing but the standard input channel and you are expected to use the keyboard to provide input or use re-direction if you do not want to type and already have your input in a file.

I don't use IDEs or projects but maybe you need to do something different about the way to indicate the arguments to the program...using re-direction may have to be specified in a slightly different manner than just a file name as an argument...maybe you can simply insert "<" before the input file name.

Alternately, attempt to run the program from a terminal:
Open a command terminal
change directories to where your input file is
execute your program calling it by full name and use re-direction to provide input, like so:
c:\path\to\executable\myprogram.exe < inputfile
