I found the following article:
Unfortunately when I tried to implement this code and compiled I received the following error:
Error 1 error #7286: This symbol has multiply declared DEC$ ATTRIBUTES ALIAS attribute. [DEBUGBREAK] 176
I'm using the Intel FORTRAN compiler.
I found using the debugbreak() in C++ to be very powerful, so thank you for any insights.
As an aside, I tried to right click on my FORTRAN executable in the Windows Task Manager and select "Debug", but that also did not work. I was a little suprised, and I believe the error message was that the file could not be found or something equivalen.
Thank you again for any feedback and insights.
