The programs generally use lists. These are objects (numbers,
variables, polynomials, etc.) written in the form
`[object,object,...]`

.
Lists are like an ordered set.

In the Grobner package and in my programs, an ideal is defined to
be a list of polynomials. This list is usually refered to as the
basis. The Grobner package calculates a standard form of this basis
with regard to the variables. The variables must also be given as a
list. To calculate a Grobner basis, use the function
`gbasis(basis,vars)`

. If you have a Grobner basis, you may
write a polynomial on its standard for using
`normalf(poly,basis,vars)`

.

The syntax in my programs are the same as above. It should be
pointed out that if you wish to view matrices, `evalm()`

should be used. Otherwise, Maple only does formal calculations.
