Replace a blank with zero

[ryanc2]

I've got a file that looks like this:

00320 MMM RAL
00321 MMM RAL
00322 MMM 1 RAL
00323 MMM 12 RAL

I need to replace the null values in the third column (position 30) with zero so the file looks like this:

00230 MMM 0 RAL
00321 MMM 0 RAL
00322 MMM 1 RAL
00323 MMM 12 RAL

Anyone have any ideas?

Thanks
