In ASP, vbscript Left string function returns the substring of specified length starting from the left side of a string. You can use also the vbscript Len function to get the number of characters in the string that returns the string length. Vbscript len function enables you to get the position of last character and retrieve the substring starting from the left side of specified string upto the character position less than the length of the string.
