Left

The Left function returns the leftmost character or characters in a text string.

Usage:

	= Left(<text> [, <num_chars>]);

<Text> is the text string containing the characters you want to extract.

<Num_chars> specifies how many characters you want the function to return. If <num_chars> is omitted, it is assumed to be 1. <Num_chars> must be positive or omitted.

Examples:

	/* Returns 'Hello'
	= Left("Hello World", 5);

	/* Returns 'H'
	= Left("Hello World");
