Assumption ... every row/record has 6 items of data, and every data item
is a number of >0 but <3 digits?
Language aside, as many can do this ...
    Read a record
        sort the record in ascending order
        write the record


The "sort the record in ascending order" could easily be done in an
array with a three point swap.
    c = a[i]
    if a[i+1] < a[i]
       a[i] = a[i+1]
       a[i+1] = c
If this must be done as alphabetic rather than numeric, add a leading 0
to all one digit number before sorting.

Hope that helps

Oops ... re-reading that I realize I forgot to mention ...
(a) do that bit (for each record) within a loop
(b) loop until no more swaps occur in that record
