Hi, I'd like to use Mathematica to run an extermal program, let me say EMFIELD.EXE with some parameters p1 , p2 : Run["EMFIELD.EXE -p1 -p2"] The external program put results in the ascii file Results.txt (a filename that I can change every time). Then I read results from it with ReadList["Results.txt", Number,...] After an analysis of them inside the same session of Mathematica, I modify the parameters p1, p2 and run again the external program. And so on for many times until analysis is OK. Since EMFIELD may take seconds or hours to generate the results, depending on the complexity of the problem and the values of parameters, how can I tell Mathematica to wait until the Results.txt file is created or updated? Pause[n] would be fine if I knew n, but this is not the case and putting a guessed large n is a poor solution (offending Mathematica lovers!). Many thanks, Roberto Roberto Brambilla CESI Via Rubattino 54 20134 Milano tel +39.02.2125.5875 fax +39.02.2125.5492 rlbrambilla at cesi.it
