        "put Galois-field element in characteristic 2, special bit 
         representation"
        SYNTAX: X = putGF2bit(Y)

        Y is an Galois-field element in characteristic 2, interpreted as 
        a polynomial in Z/2Z.
        putGF2bit displays a sequence of 0 and 1, interpreted as the
        coefficients of this polynomial in Z/2Z.
        (For example the string 100101 represents the Galois-field  
        element GF(A^5 + A^2 + 1) if 'A' is the specified variable.)

        X is assigned Y. 

        GF(2^n) is specified by "curgf" or "curgf2bit".
        For additional information on working with the current Galois- 
        field, please type "? curgf" or "? curgf2bit".


        Example 1: (correct)

                putGF2bit( GF(A^2+1) )
