Thank you, you are really helpful. But I do not want to run glomosim.exe , what I want is to run the command (glomosim data.in) on CMD.exe ! So I tried to write : 

my @args = ("c:\\Windows\\System32\\cmd.exe","c:\\glomosim\\bin\\data.
+in");  
       system(@args) == 0 or die "system @args failed: \n syscode:$? \
+n error:$! \n";

but I get nothing !! Microsoft windows version ..... etc ! How I can pass a command (glomosim data.in) to cmd.exe ? Thank you very much.
