Syntax

Extracting the last characters from a string Hide the details

<Result> = Right(<Initial string> [, <Length>])
<Result>: Character string
  • Last characters 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
String from which the last characters 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 last characters of a string buffer Hide the details

<Result> = Right(<Initial buffer> [, <Length>])
<Result>: Buffer
  • Last characters of <Initial buffer>. Corresponds to <Initial buffer> if <Length> is greater than <Initial buffer>.
  • EOT if <Length> 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 string buffer from which the last characters will be extracted. This buffer is not modified.
<Length>: 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 uses two bytes.. Therefore, the memory size of 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.
