Syntax

Retrieving the size of a variable Hide the details

<Result> = Dimension(<Variable name>)

<Result>: Integer

Requested size.
Pascal string Number of useful characters in the string.

Example: For a Pascal string on 10, the result will be 10.
ASCIIZ string Number of useful characters in the string.

Example: For an ASCIIZ string on 10, the result will be 9 because there is a binary 0 at the end.
Composite variable and structure Sum of the size (in bytes) of each component.

Caution: This case does not apply to the Classes.
Array Total number of elements in the array. This function is equivalent to the Count property.

Example: For an array of 3 strings, the result will be 3.
Example: For an array of 5 by 3 integers, the result will be 15 (5 * 3)
Remark: To find out the size of array dimensions, use ArrayInfo.
Other Size in bytes of the memory area corresponding to the variable. For the character strings, use Length.

<Variable name>: Character string

Name of the variable (any type of variable).

Resizing a dynamic array of N dimensions Hide the details

Dimension(<Array name> , <Number of elements in dimension 1> [, <Number of elements in dimension 2> [... [, <Number of elements in dimension N>]]])

<Array name>: Character string

Name of the variable that corresponds to the dynamic array.
Remark: The fixed arrays cannot be resized.

<Number of elements in dimension 1>: Integer

Number of elements in the first dimension of the array.
Caution: The number of array dimensions cannot be modified, nor the type of the elements. A two-dimensional array remains a two-dimensional array.

<Number of elements in dimension 2>: Optional integer

Number of elements in the second dimension of the array.
Caution: The number of array dimensions cannot be modified, nor the type of the elements. A two-dimensional array remains a two-dimensional array.

<Number of elements in dimension N>: Optional integer

Number of elements in the Nth dimension of the array.
Caution: The number of array dimensions cannot be modified, nor the type of the elements. A two-dimensional array remains a two-dimensional array.

Resizing a dynamic array of N dimensions Hide the details

Dimension(<Array name> , <Number of elements in dimension 1> [, <Number of elements in dimension 2> [... [, <Number of elements in dimension N>]]])

<Array name>: Character string

Name of the variable that corresponds to the dynamic array.
Remark: The fixed arrays cannot be resized.

<Number of elements in dimension 1>: Integer

Number of elements in the first dimension of the array.
Caution: The number of array dimensions cannot be modified, nor the type of the elements. A two-dimensional array remains a two-dimensional array.

<Number of elements in dimension 2>: Optional integer

Number of elements in the second dimension of the array.
Caution: The number of array dimensions cannot be modified, nor the type of the elements. A two-dimensional array remains a two-dimensional array.

<Number of elements in dimension N>: Optional integer

Number of elements in the Nth dimension of the array.
Caution: The number of array dimensions cannot be modified, nor the type of the elements. A two-dimensional array remains a two-dimensional array.
