That's strange. You mean when you entered "asdf" as a line of STDIN, it looked like the program was reading and processing after the read line, but if you entered correct input there was no output?

Maybe the output is being eaten too. Try writing to a file rather than STDOUT (try STDERR too, since that's where the warnings went), and see if results appear.

If that's the case, ditch COMMAND.COM and download 4NT.exe as your command shell. If that doesn't help, upgrade the OS. The console in Win9x is a Frankenstien monster of 16-bit DOS spliced together with "virtual device drivers", and it's known for being cranky.
