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.
