[ 3 ] Array Declaration

This is a declaration statement for an array. An array can be created for all

types except for an I/O variable by adding a postposition to a variable name.

However, an array cannot be initialized together with the declaration.

The subscript of an array must be 0 or more. The array can be up to 3

dimensions.

The upper limit of the total number of elements for an array is 32767.

Array Declaration

Type Command Example

Array declaration DIM DIM AA (10,10)

Example of array declaration:

DIM CC (3,3,3) AS INTEGER 'Sets CC to 3-dimensional array of an

integer

'type.

The above example can be expressed as follows by the use of a DEFINT

command.

DEFINT CC (3,3,3) 'Sets CC to 3-dimensional array of an

integer

'type.

Note: Difference between DEF??? statement and DIM statement

A DIM statement can be used for more than just an array.

For example, instead of

DEFINT CC,

Express as follows.

DIM CC AS INTEGER

Since it cannot be initialized at the same time as the type

declaration, a DIM statement is more universal than a DEF???

statement. For example, the following expression cannot be

created using a DIM statement.

DEFINT CC = 1 'Declares CC as an integer type and sets

the initial value to 1.

If it is not initialized together with the declaration, all types of

arrays can be handled in the same manner. Therefore, using a

DIM statement is recommended.

[ 4 ] I/O Variable Declaration

A variable name corresponds to a specific I/O port.

I/O Variable Declaration

Type Command Example

I/O variable declaration DEFIO

DEFIO PORT =
