When using Optimus to call the software, this error is prompted, and the file is libifcoremd.dll. How should I modify it?  The error is

Is the file "g1_setsinglewindo 985 g1_etc.f" your file? This is where the error originates. You need to look at that you have a write statement that is in error. 

[Ron_Green]

if you add these options

/debug:full /traceback

you can get a more readable stack trace that will point you to the write or print statement that is the problem.
