Hi Rob,
Thanks for that. I have spent 30 mins on it and was pulling out my hair. The
end of the heredoc had a tab in front. I didn't know this mattered. I had the
"tag" included and removed for the heredoc. But I got an error when compiled
without the quotes around the Heredoc tag. Now I know why. This is the first
time I ever have used heredocs.
Far better then other ways I have done it.
It all works now.
