[plt-scheme] new to programming

[anesmike]

OK i am new to this and my question is : on page 10 of htdp ; there is
a question concerning convert-repl which is a program that maps a
fahrenheit to celcius program to a list of numbers.but the problem is
there is instructions on creating a list of numbers. any help would be
appreciated.
thanks,mike
