Tables

5.1 Objective

To become familiar with table driven code.

5.2 What you should do

You will have to turn in your LST ﬁles for the programs you write for this lab.

Check with the TA for additional instructions. In most of the examples, the name

is left blank as _____________. Make sure you enter your name in its place.

5.3 Tables

What is a table? Technically, table is same as an array except we use the term

table to refer to arrays whose elements are constants. To operate on the table, we

need two pieces of information, where, in memory, the table starts( the starting

address) , and how many elements are in the table ( the size or dimension).

In this lab, we will initially consider the case where each element requires one byte

of memory.

5.4 Setting up a table

To setup a table in memory, we generally use FCB, FDB and FCC. For example, if

we want to setup a table of prime numbers, we would write (using decimal since

it is easier to read):

...

1 2 ... 54 55 56 57 58 59 60 61 62 63 64 ... 100 101
