Comments: When

the

BASIC

interpreter

encounters

a

DIM

statement,

it

initialises

all

the

elments

of

the

array

to

zero,

if

it

is a

numeric

array

.

For

a

string

array,

all

elements

are

initially

null

strings

(i.e.

empty

strings).

However

the

length

of

each

element

can

be

different

as a

result

of

program

execution.

If

an

array

is

used

in

a BASIC

program

without

a

corresponding

DIM

statement,

the

interpreter

assumes

the

value

of

the

subscript

to

be I 0.

The

maximum

number

of

dimensions

and

maximum

number

of

elements

in

each

dimension

depend

on

the

amount

of

free

memory

in

the

system.
