The LIST command tells thecomputer to display
the program currently in its memory. The LIST
command is especially useful when writing long
programs, because you can check for errors that
your computer can't catch-like misspelling a
word or inserting an incorrect number.
If you want to type a different program into
your computer now, you /lave to erase this pro-
gram from your computer's working memory. To
dO this, you use another BASIC command, the
NEW command. NEW tells the computer that
you want to type in a whole new program. Your
computer erases the program presently in its
working memory and gets set for a
new program.
Even though we aren 't going to type a new
program into the computer right now, let's try
the NEW command to
see
how it works. Simply
type the word
NEW
The command appears on the screen.
