 MOD()*
 Return the dBASE III PLUS modulus of two numbers
------------------------------------------------------------------------------
 Syntax

     MOD(<nDividend>, <nDivisor>) --> nRemainder

 Arguments

     <nDividend> is the dividend of the division operation.

     <nDivisor> is the divisor of the division operation.

 Returns

     MOD() returns a number representing the remainder of <nDividend> divided
     by <nDivisor>.

 Description

     MOD() is a numeric function that emulates the dBASE III PLUS MOD()
     function.  It is implemented using the CA-Clipper modulus operator (%).
     Note that there are differences between the dBASE III PLUS MOD()
     function and the CA-Clipper modulus operator which are described in the
     following table:

     MOD() is supplied as a compatibility function and therefore not
     recommended.  It is superseded entirely by the modulus operator (%).

 Notes

     .  Zero divisor in dBASE III PLUS: In dBASE III PLUS, a zero
        divisor returns the dividend for every value of the dividend.  In
        CA-Clipper, by contrast, the modulus of any dividend using a zero
        divisor causes a runtime error.

     .  Zero divisor in earlier versions: In versions of CA-Clipper
        prior to Summer '87, a modulus operation with a zero divisor returned
        zero for all dividends.  In Summer '87 and later versions, it returns
        a runtime error.
