INDEX

    Locates a character or a substring within a string and returns its
    location within the string.

 Syntax

    integer := INDEX (string1, string2)

 Parameters

    string1    The string within which you want to find a character or a
               substring.  Put the string in quotes.

    string2    The character or substring whose leftmost character location
               you want to find within string1.  Put the string in quotes.

 Example

    loc := INDEX ("1234567", "67")

    Stores an integer value of 6 in the variable LOC, since the substring
    67 is found starting at character position 6 within the string 1234567.
