Most text processing commands (eg. grep, awk) have a maximum line length limit
on z/OS. The current method of using cc -E & grep fails on z/OS because of
this limit. I'm changing the command to create the long line in the response
file to use python. This avoids the possibility of any tools blocking the
generation of the large response file.
