back and forth data to & from Fortran

[UofH]

there is a standard program in fortran in my lab to calculate reflection ceofficient but the program needs input from the analyzer. LV program is written to get the data but can I extend the program to feed the data to FORTRAN as well? and also get back the result after executing in fortran (and mayb show it on the front panel..)?

as of now, we write the data to excel and feed it to fortran manually.

Is it possible that your FORTRAN program accepts command line inputs?

If so, you might be able to use the System Exec vi.

You may also want to try using the call library function (DLL) or CIN nodes in LV.   Here is a related discussion:

 How can I use Fortran source code in CIN?

But direct communication between Fortran and LabVIEW is not supported.
