I forgot to mention that the processing does not require all 28Mb in
memory the file contains approx 17,000 records - the largest record is
about 5K. The processing is as follows:
open input file
open output file
while not EOF input file
create input record object
read next input record
create output record object
map input record -> output record
write output record
destroy input record
destroy output record
close input file
close output file
