[Haskell-cafe] little help please

[Nicolas Wu]

This compiles:

import System.Environment(getArgs)
import System.Process(readProcessWithExitCode)
import System.Exit(exitWith,ExitCode(ExitSuccess))

main = do
  args <- getArgs
  (ecode,out,err) <- readProcessWithExitCode
"c:\\Perl64\\bin\\perl.exe" ("C:\\Program
Files\\MySQL\\scripts\\mysql_config.pl" : args) ""
  if ecode == ExitSuccess
    then return out
    else return err
  exitWith ecode

I had trouble with the spacing you had when I pasted your code, and
also changed the imports so that ExitSuccess was being imported.

All the best,

Nick
