Pressing [ENTER] has the effect of [ENTER]ing the command or program line you have just typed
into the.computer, and then asking the computer to process the in-struction contained on that line -
or if the line began with a number, then to store it away as part of your program.
[ENTER] is also sometimes referred to as the ' carriage return' or simply ' return' : which is a reference
to the early forms of computer terminals which were based on mechanical typewriter principles. The
term has remained, and is enshrined forever in the ASCII character set, where the code for [ENTER]
is annotated by the letters ' CR' . Type in:
1 0 F O R N = 3 2 T O 2 5 5
2 0 P R I N T C H R $ ( N ) ;
3 0 N E X T N
