SizeOf Function

Purpose

Returns the size of a variable or a user-defined type.

Syntax

SizeOf(a)

a:variable or user-defined type

Description

SizeOf returns the number of bytes a variable or user-defined type occupies.

String variables always return 4, and Variant variables always return 16.

For an array only the size of an element can be determined.

Example

Strings

OpenW 1

Local a$, x%, b As String*10000

a$ = Space$(1000)

Print SizeOf(a$) // prints 4

Print SizeOf(b) // prints 10000

Print Len(a$), Len(b) // prints 1000, 10000

Type variables

OpenW 1

- UByte d(5)

- Variant e(5)

- Double f(5)
