replacing characters with awk/substr

[qusan]

Would using awk's substr in this manner be feasible? I am trying to replace characters 35-42 with zeroes for every record in a file.


runid = substr($0,35,8)
zeroed ="00000000"
runid=zeroed

Try something like this:
awk '
{print substr($0,1,34)"00000000"substr($0,43)}
' /path/to/input > output

Hope This Helps, PH.
