Extracts the right part (i.e., the last characters) from a string or buffer.
WEBDEV - Browser code In this version, the right part of a buffer cannot be extracted.
Example
// Extract characters
Right("The cuckoo", 6)   // Returns "cuckoo"
Right("ABC", 50)   // Returns "ABC"
Right(" AZELMA")   // Returns "AZELMA"
 
MyString is string = "Antananarivo - Madagascar"
Right(MyString, 10) // Returns "Madagascar"

Syntax

Extracting the right part of a character string Hide the details

<Result> = Right(<Initial string> [, <Length>])
<Result>: Character string
  • Right part of <Initial string>. Corresponds to <Initial string> if <Length> is greater than the length of <Initial string>.
  • EOT if <Length> is negative. A WLanguage error occurs (non-fatal error). To get more details on the error, use ErrorInfo.
<Initial string>: Character string
Character string from which the right part will be extracted. This string is not modified.
<Length>: Optional integer
Number of characters to extract. If this parameter is not specified, <Result> corresponds to <Initial string> without leading spaces.

Extracting the right part of a buffer Hide the details

<Result> = Right(<Initial buffer> [, <Size>])
<Result>: Buffer
  • Right part of <Initial buffer>. Corresponds to <Initial buffer> if <Size> is greater than the size of <Initial buffer>.
  • EOT if <Size> is negative. A WLanguage error occurs (non-fatal error). To get more details on the error, use ErrorInfo.
  • Invalid buffer if <Initial buffer> contains a UNICODE string.
<Initial buffer>: Buffer
Name of the buffer from which the right part will be extracted. This buffer is not modified.
<Size>: Optional integer
Number of bytes to extract. If this parameter is not specified, <Result> corresponds to <Initial buffer> without leading spaces.
Remarks

Right and UNICODE

If the string passed as a parameter is an ANSI string, the result will be an ANSI string.
If the string passed as a parameter is a UNICODE string, the result will be a UNICODE string.
Reminder: In UNICODE, each character occupies two bytes of memory. Therefore, the memory footprint of a UNICODE string is twice the number of characters actually contained in the string.
The fist character in the string is at index 1.
Remark: If the result on an ANSI string is assigned to a UNICODE string (and conversely), the conversion will be implicitly performed.
For more details, see Managing UNICODE.
