Java can invoke the OS which will in turn launch the FORTRAN program. You
can connect to the input, output and error streams of the program also, if
you want. Look for Runtime.exec () and a new helper called ProcessBuilder.
There are some gotchas, but you can find sample code, etc by searching the
web or this newsgroup.
