Solved: Executing a Windows program during a Fortran run - Page 2

Paulo_M_ · ‎03-12-2015

Hello everyone,

I am working on an optimization code, in which an external program should provide a data file, to be read by Fortran. My question is: how could I execute the external program during the Fortran run?

Thanks,

Paulo

Paulo,

You can call any command using SYSTEMQQ, which takes as an argument the command that you would use in a command or batch file.

Obviously, you would need to make sure your Fortran program closes any files needed, then you can call the program with a statement like

CALL SYSTEMQQ("C:\foldername\myprogram.exe argument1 argument2")

Then, when the program has completed, you can open the files to be analysed by your Fortran program.

Regards,

David

EXECUTE_COMMAND_LINE would be more portable, but you'd need to find a replacement for Wordpad on Linux.

export dboggs_EDITOR=gedit

IOW use an environment variable to provide the (partial) string for the EXECUTE_COMMAND_LINE.

You still have to work out issues regarding option switches and/or path separators /, \.
