Syntax

Extracting the right part from a character string Hide the details

<Result> = Right(<Source String> [, <Length>])
<Result>: Character string
  • Right part of <Source String>. Corresponds to <Source String> if <Length> is greater than the length of <Source String>.
  • EOT if <Length> is negative. A WLanguage error occurs (non-fatal error). To find out the error details, use ErrorInfo.
<Source String>: Character string (with quotes)
Character string whose right part must be extracted. This string is not modified.
<Length>: Optional integer
Number of characters to extract. If this parameter is not specified, <Result> corresponds to <Source String> without the space characters on the left.

Extracting the right part from a buffer Hide the details

<Result> = Right(<Source Buffer> [, <Size>])
<Result>: Buffer
  • Right part of <Source Buffer>. Corresponds to <Source Buffer> if <Size> is greater than the size of <Source Buffer>.
  • EOT if <Size> is negative. A WLanguage error occurs (non-fatal error). To find out the error details, use ErrorInfo.
  • Invalid buffer if <Source Buffer> contains a character string in UNICODE format.
Windows Mobile Invalid buffer if <Source Buffer> contains a character string in ANSI format.
<Source Buffer>: Buffer
Name of buffer whose 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 <Source Buffer> without the space characters on the left.
Windows Mobile In UNICODE, each character occupies two memory bytes. Therefore, the number of bytes is twice the number of characters.
Remarks

Right function and UNICODE

If the string passed in parameter is in ANSI format, the result will be in ANSI format.
If the string passed in parameter is in UNICODE format, the result will be in UNICODE format.
Reminder: In UNICODE, each character occupies two memory bytes. Therefore, the memory footprint of a UNICODE string is twice the number of characters actually found in the string.
In UNICODE, the subscript of the first character in the string is set to 1.
Note: If the result on an ANSI string is assigned to a UNICODE string (and conversely), the conversion will be implicitly performed.
See Managing the UNICODE format for more details.
Windows Mobile

Different operating mode in GO mode and at run time

In GO mode (simulation on the development computer), when extracting the right part of a buffer (syntax 2), <Size> corresponds to the number of characters to extract and not the number of bytes.
For example, running the following code:
MyBuffer is Buffer = "WINDEV is tremendous"

Right(MyBuffer, 10)
  • in GO mode, returns "tremendous".
  • in real use, returns "ndous".
The differences between GO mode (simulator) and real use are presented in Differences between GO mode and real use.
