Returns an integer, 0 through 4, which represents the relative phonetic difference between two character expressions.

DIFFERENCE(cExpression1, cExpression2)


cExpression1, cExpression2

Specifies the character expressions that DIFFERENCE(В ) compares.

Return Value



DIFFERENCE(В ) is useful for searching tables when the exact spelling of an entry isn't known.

The more alike the two expressions are spelled, the higher the number DIFFERENCE(В ) returns. If the character expressions are spelled very similarly, DIFFERENCE(В ) returns 4. For two character expressions with little in common phonetically, DIFFERENCE(В ) returns 0.
