CHAPTER 4 Programming with BASIC Language
<
DIM mode and DEFM mode >
It will not be possible to specify an array by a DIM statement and a DEFM state-
ment at the same time. That is , the computer will select either the DIM mode or
the DEFM mode and will display the mode such as "DEFM" if in the DEFM
mode. When power is switched ON, the computer will revert to the state it was in
before power was switched OFF. If a DIM statement was executed, it will revert
to the DIM mode and, if a DEFM statement was executed, it will revert to the
DEFM mode .
<
Precautions when Switching Over>
Precautions will be required when switching modes since the array declared with
DIM will be cleared when switching from the DIM mode to the DEFM mode,
and the array declared with DEFM will be cleared when switching from the
DEFM mode to the DIM mode.
<
Array Declaration with a DIM Statement >
This computer is capable of declaring array variables of up to three dimensions.
These array variables consist of two types which are the character array variables
and the numeric array variables .
1) Declaration of one-dimensional array variables
A DIM statement is used to declare array variables and a one-dimensional
array variable will be specified as follows.
DIM A(10)
*The numeral 10 in parenthesis is called a
subscript.
There are 11 elements in this array consisting of A(O), A(l ), A(2), . . . A( 10).
These array elements exist independent of variables such as A, B, C, etc.
which are numeric variables. A CLEAR statement or ERASE statement is
therefore used when clearing these arrays. When declaring two array variables,
punctuate the array variables with a comma.
DIM A(3) , 8(3)
