Print
If you have a suitable printer connected,
this lets you print out the current program
on paper.
If no printer is connected, or there is
some other problem, the computer may
appear to 'freeze'. it can be cleared by
pressing [BREAK]. When printing is
complete, you will be returned to the
program screen.
Exit
This option returns you to the main menu.
Your current program is automatically
stored and will be recalled if you select 128
BASIC again. If you switch off, select 48
BASIC or press the reset button the program
will be lost.
USING THE CALCULATOR
The number keys and mathematical
symbols on the keyboard or keypad can be
used exactly like an ordinary pocket
calculator, by selecting the Calculator
option from the main menu.
When you select the option, you will see
the blank Calculator screen. Now just type
in your calculation in standard
mathematical notation. For example, type
27*45
When you press [ENTER] the answer =
1215 will appear. As on an ordinary
calculator, the current result is held in the
Spectrum's memory  so if you want to
carry out further calculations, there is no
need to retype it. For example, to take 685
from the answer you just got, you type
685
and press [ENTER] to see the answer =
530.
The calculator uses all the mathematical
functions available in Spectrum BASIC (see
the ZX Spectrum + User Guide). The
keypad has the four main mathematical
functions * / +  and also supports the
use of brackets.
When you have finished with the
calculator, you can return to the main
menu by pressing [EDIT]. This brings up
the Options menu:
Select Calculator to return to the Calculator
screen, or Exit to return to the main menu.
