In french: Gauche
Extracts the left part (i.e., the first characters) from a string or buffer.
In this version, the left part of a buffer cannot be extracted.
Left("The cuckoo", 6) // Returns "The cu"
Left("ABC", 50) // Returns "ABC"
Left("AZELMA ") // Returns "AZELMA"
MyString is string = "Developing is child's play"
Left(MyString, 10) // Returns "Developing"
Extracting the left part of a character string Hide the details
<Result> = Left(<Initial string> [, <Length>])
<Result>: Character string
- Left 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 left 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 trailing spaces.
Left 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.
