Perl's extensions to the RE vocabulary are helpful here ([b]WARNING: untested code[/b):
Code:
perl -pe '/^(.{96}).{10}(Y.*)/ && do { $_ = $1 . " " x 10 . $2 }'

This takes adavntage of the -p option, which prints $_ after processing each record.

Or you can combine oombera's separate invocations of awk into one:
Code:
awk 'substr($0,107,1) == "Y" { $0 = substr($0,1,96) "          " substr($0,107,length($0) - 107) }
{print}' someFile > newFile
mv newFile someFile

Awk is still record length limited AFIAK, so if your records are very long (> 8K ?), you may not be able to read entire lines (I was bitten by this earlier this week).
