EdGCM (http://edgcm.columbia.edu) runs a lot of FORTRAN from inside RB. But
you see the gory details, it is not hidden.
I call shell commands by just appending them and then calling it once:
s = "rlogin node1; cd dir/a; nohup ./runit &; exit"
shell.execute( s )
You could also write your commands to a shell script from RB then call the
script. Now it isn't hardcoded but dynamic.
-k.
