  unexpected end of file (Message 1 to 3 of 3)

When I render the scene given below, I get the error message "unexpected end
of file". This only happens when there comes  absolutely nothing after
"#end". As soon as I put in a space or a new line the scene will render.

WinNT 4 & SP3

This is a common problem for a lot of languages.  So much so, in fact, that
people in at least one other newsgroup will tell you that if your editor 
allows you to create a text file with no newline after the last line, then 
the flaw lies in your editor, not in the parser.  I tend to agree with them.

It is so easy to change a parser to check for this condition
that the fact it is a common problem doesn't make it not a problem,
however.

There are valid reasons that one might want to omit a newline
from a file end.   But I can think of no reason a parser
would not want to conclude EOF was a line terminator (unless
this is viewed as some sort of scheme to catch truncated
files)

So I agree with "ingo" that this is validly called a bug.

Dan

P.S. Thanks for the LINUX port, but that's for another group...
