Error Replacing '-' by 0 in a file


I have the following data in my file (file.csv):,21 September 2009,ace,42,0,0,0,-,-,21 September 2009,adb,3,0,0,0,-,-,21 September 2009,agp,3,0,0,0,-,-,21 September 2009,alc,23,0,0,0,-,-

I need to prepare a UNIX script, where the '-' can be relaced by zero (0) throughout the file length.

Please advice.
