Lesson 3: Entering Characters
There
are
over
200
characters available on
the HP 48. They
can
be
used in text strings
and, with a few restrictions, in variable names
and
equations. Most
of
these
characters are available on tile
Alpha (@)
keyboard, and all are
accessible using
the
CH ARS
feature.
The Q Keyboard
The @ key is a special shift key that converts the
keylioard into a kind of typewriter. Whenever you see the
d. annunciator at the
top
of the
display, the
next
key you
liress will type its alpha character instead of performing
its operation.
Only the up|)er-case English letters are printed on the keyboard (in
white at the lower-right corner of the respective key).
You can turn on the Ot animiiciator (that is, enl.er
a l p h a m o d e )

ways, depending
