Sort/select processing when sorting by associated fields

[Kenneth Brody]

If you have a file with 100 records, and each record has 5 non-blank
instances of the associated field on which you are sorting, then the
sort/select processing will be run 500 times, not 100.  It will be
run for each non-blank instance of the associated field used for the
sort.  (This allows you to select only certain instances from within
your sort/select processing.)  If all instances of the field are
blank within a given record, the first instance will be selected.

You can verify this by creating a simple file.  For ease of setting
this up, create a file with five instances of A1, and add 5 records
filling in only 3 instances for each record.  Then, create an output
sorted on A1.  Finally, create a sort/select processing:

    mesgbox "Record " < @rn { "\n at AF = " < @af { "\nA1 = " & A1

When you run the output, you will see that your processing is run
15 times -- one time for each non-blank instance of A1.
