Guenter and Joel
I appreciate your help but I am coming to the conclusion that the pdf file
format is not well enough defined to be able to reliably embed software
listings that the reader can copy/paste into a file and then be able to compile
the results. I will have to continue as I have done in the past to include a
listing in the pdf but also to provide a link to a supplementary online zip
file with the source code in text files.
Bob
p.s.
Guenter, here are the answers to some of the questions in your response:
>Does it show up as hyphen or as question mark in the PDF?
It is displayed as a '-' in the pdf but copy and paste of the 3 characters in
the listing results in x?y with '?' being 3F hex according to my editor.
>Which fonts does your PDF use?
I do not know how to answer that question. How do I find out what fonts it uses?
>What is the result if your listing contains: ...
Here is what I get if I enter your list into the listing, create a pdf then
copy and paste the text in the listing.
