  • Read-char - reads a file character by character, returning the ASCII code - slower but more exacting
• To convert a string that looks like a list to a list, use the (read)
• Remember to close files when you are done with them
  • Open files cannot be read by you or anyone else until they are closed
  • Open files, if left to excess, can corrupt your hard drive
  • Just like selection sets, you can only have so may files open at once
