INSTRING( )
Rick Borup
INSTRING() searches for an occurrence of one string in another string. Unlike VFP's "$" function, INSTRING() treats the searched string as a series of substrings whose length is equal to the length of the string being sought. This is useful for validating codes that are greater than one character in length. For example, if "AB" and "CD" are valid values for some field, INSTRING("BC", "ABCD") returns .F. whereas "BC" $ "ABCD" returns .T.   In contrast to INLIST(), INSTRING() requires only a single parameter for the validation string. This allows you to store the validation string in a single table field.
