I know, but the various functions that create processes don't help me know whether the program actually ran or not. For example, > createProcess (proc "nosuch" []) >>= \(_,_,_,ph) -> waitForProcess ph returns ExitCode 127. If I use the same code to run 'test', a C program that returns 127, I get the same thing. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
