You are one infraction away from being set read-only. Please start using code tags.
awk doesn't work like that, it's for delimited files, not fixed-width ones. You can assign text to column numbers, but you can't assign it to the return of a function.
If you have GNU awk, you could do awk -v FIELDWIDTHS="width1 width2 width3 ..." '$5 ~ /-/ { $5="000000" } 1' inputfile outputfile, with 'width1' etc replaced by the widths of your columns, and 5 replaced by your column number... FIELDWIDTHS is a special variable GNU awk uses to deal with fixed width files.
