I gave you some program fragments to help you get started. You are
going to have to use those fragments in the context of a working
program. You need to understand what each of those program fragments
does and how they should relate to your whole program.

I forgot the closing double quote on the above line. Sorry. If you
fix that line, the program should compile OK.'
The $outputfile variable is not defined here, and does not have a
value. You said you wanted a file name with a time tag, so it is up
to you to add the statements to define $outputfile the way you want
it.

The above line should probably not be inside the loop, as it
represents a header line at the beginning of the output file.

Most of the errors are probably a result of not closing the quote.
