I used TemplateStudio to edit the template.
Odd thing is the "extra chars" only occur when I run "single task" to create the output; if I choose "Generate Task" they don't occur.
I also went thru all the templates (as recommended by Frans) and saved them as ASCII to ensure they didn't have any "extra chars" in them either.
Since I have done that, I am not having any issues.
Thanks for the tips, both of you.
Andrew.
