This chapter provides a handy reference guide to BASIC's key definitions for the
HP 98203A keyboard. Keep in mind that other system programs may define the keys
differently. Each key will be demonstrated where possible. One point to clarify: the
cursor that we refer to in the following paragraphs is the blinking-underline that points
to a location on the screen.
Note
Before you proceed, type:
SCRATCH
I
EXEC
I
This clears the computer of any programs that might be left in
memory from previous demonstrations.
