Chapter 1. Introduction
ABOUT THIS MANUAL
This manual will show you how to operate the 5110 using the BASIC
language.
If you are already familiar with the BASIC language, you
may be able
to skip most of the language-only topics and simply learn
how to operate the 5110. If you are not familiar with the BASIC
language, you should read
the manual from cover to cover while
performing the suggested keying operations or examples on your
5110. Not all of the features and functions of the BASIC language are
discussed in this manual. For
more information about the 5110 or the
BASIC language, see the
IBM 5110 BASIC Reference Manual,
SA21-9308, or the IBM 5110 BASIC User's Guide, SA21-9307.
This manual assumes
that your 5110 has been installed and checked
out.
If this is not the case, use the IBM 5110 Customer Setup Manual,
SA21-9318, to install your system.
ABOUT BASIC
BASIC is an interactive computer language; that is, whatever you enter
into the system is processed immediately. BASIC has many built-in
functions that allow you to effectively solve your problems. BASIC
also allows
you to write programs using BASIC language statements
and facilities. These programs can be stored on
the tape cartridge or
diskette for later use.
BASIC is a
good language to experiment with. Nothing you do from
the keyboard can damage the system; and the more you experiment,
the more you will learn about BASIC and the system.
ABOUT THE 5110
The 5110 Model 1 (Figure 1) is a computer designed to help solve your
business problems. The display screen and indicator lights
communicate
information to you, and the keyboard and switches allow
you to control the operations the system will perform. The 5110
Model 2 is identical to the 5110 Model 1 except that it does not
contain the built-in tape unit.
Before you begin
to use the 5110, you should become familiar with the
keys and
the control panel {Figure 1}. The control panel consists of a
series
of switches, which will be explained later.

What follows is a brief description of the keys. How you use the keys
will be described later. For now, familiarize yourself with the names
and locations
of keys on the system. Figure 2 shows a BASIC-only
keyboard, and Figure 3 shows a combined BASIC/APL keyboard.
If your system is equipped to operate either BASIC or APL programs,
you may
be unfamiliar with the symbols appearing at the top and on
the
front of the alphameric keys (Figure 3). For BASIC operations,
even on a BASIC-only machine (Figure 2) where they are not shown
on the key top, these symbols can be displayed or printed, although
their APL functions
do not apply to BASIC operations. See the IBM
5110 BASIC Reference Handbook, GX21-9309, for the APL characters
and their locations.

Alphameric Keys
The alpha keys are similar to those on a standard typewriter, except
that there are no lowercase characters. The alpha characters are all
uppercase, even though
they are in the lowercase position on the
keys. Thus, you do not use the shift key for alpha characters.
If you want to enter an upper-shift character, you must hold down the
shift key and then press the key to enter the character, just as you
would to type an uppercase character on an ordinary typewriter.
You can also enter lowercase alphabetic characters
from the keyboard.
How you enter lowercase alphabetic characters is discussed later in
this chapter.
Numeric Keys
Either the top row of alphameric keys or the special calculator
arrangement of numeric keys on the right of the keyboard can be used
to enter numbers.

BASIC Command Keywords
The words listed above the top row of alphameric keys (1-0) are
BASIC command keywords that you can enter by holding down the
CMD key and then pressing the key below the desired command. For
example,
to enter the LOAD command keyword, hold down the CMD
key and press
1. These commands and their use are described later.
BASIC Statement Keywords
Notice the special character combinations of BASIC keywords
engraved on the front of the alphabetic keys. If you have a combined
APL/BASIC machine, there is also an APL special character
combination on the
front of the key. You can enter the BASIC
keywords by holding down the CMD key and then pressing the
appropriate key. You
will see how these BASIC keywords are used as
you become familiar with the BASIC language.
BASIC Statement Keyword
APL Special
Character Combination
Note: You can use the APL special character combination only when
you are using your system as an APL machine.
Arithmetic Operator Keys
The four keys to the right of the calculator arrangement of numeric
keys are the arithmetic operator keys that are used to perform
division, multiplication, subtraction, and addition. These operator keys
also appear on the alphameric keyboard. In BASIC the symbol/is
used for division, and the symbol * is used for multiplication.
