I am trying to write a program that takes a text file (it prompts you for
the file name)  and creates a new file (adding a .ent extension) with the
same text , but converting ANSI characters to character entites. This almost
works, but it seems only to convert the even numbered lines in the file. Is
this because "oldfile.readline()" is called twice in my control loop? If so,
how do I avoid this? Could someone please take a look at this for me (file
attached). Thank you.

P.S. I realize someone has probably already written a program like this, but
it is still a great learning experience for me.
