Returns the first n characters in a source string.
result=Left(source, count) OR
|result||String||The first count characters of source.|
|source||String||The source string from which to get the characters.|
|stringVariable||String||The String variable from which to get the characters.|
|count||Integer||The number of characters you wish to get from source.
If count is greater than the number of characters in source, all characters are returned.
|stringVariable||String||Any variable of type String.|
The Left function returns characters from the source string starting from the left side (as the name implies).
If you need to read bytes rather than characters, use the LeftB function.
This example returns the first five characters in a string.
s=Left("Hello World", 5) //returns "Hello"
s=s.Left(5) //returns "Hello"
