Returns an integer, 0 through 4, which represents the relative phonetic difference between two character expressions.
Syntax
DIFFERENCE(cExpression1, cExpression2)
Returns
Numeric
Arguments
cExpression1, cExpression2
Specifies the character expressions that DIFFERENCE( ) compares.
Remarks
DIFFERENCE( ) 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( ) returns. If the character expressions are spelled very similarly, DIFFERENCE( ) returns 4. For two character expressions with little in common phonetically, DIFFERENCE( ) returns 0.
