Returns:
  • the size of a character string, which means the number of characters found in the character string (including the space and binary 0 characters).
  • the size of a buffer, which means the number of bytes found in the buffer.

Syntax

Size of character string Hide the details

<Result> = Length(<Source string>)
<Result>: Integer
Number of characters found in the string.
<Source string>: Character string
Character string whose size will be calculated.

Size of buffer Hide the details

<Result> = Length(<Source buffer>)
<Result>: Integer
Number of bytes found in the buffer.
<Source buffer>: Buffer
Buffer whose size will be calculated.
Windows Mobile In UNICODE, each character occupies two memory bytes. Therefore, the size of a buffer containing a UNICODE string is twice the number of characters actually found in the string in Windows.
LinuxiPhone/iPadApple Watch In UNICODE, each character occupies four memory bytes. Therefore, the size of a buffer containing a UNICODE string corresponds to four times the number of characters actually found in the string in Windows.
Remarks
Windows Mobile

Operating mode in GO mode and at runtime

In GO mode (simulation on the development computer), when Length is used on a buffer (syntax 2), <Result> corresponds to the number of characters found in the buffer, not to the number of bytes.
For example, running the following code:
MyBuffer is Buffer = "WINDEV is astonishing"
Length(MyBuffer)
  • in GO mode, this code returns 21.
  • at runtime, this code returns 42.
The differences between GO mode (simulator) and real use are presented in Differences between GO mode and real use.
