HELP ERASE                               updated Mark Rubinstein  October 1985

This may seem a silly procedure - when called it returns all its arguments
except for the last!  For example:

    erase(1,2,3) =>
    ** 1 2

However, it is often useful  if you want to use only one of the results of a
procedure which produces two results or wish to ignore the result of some
procedure. For example, to ignore one input character do:

    erase(charin());

To  find the remainder of an integer division do:

    erase(20 // 3) =>
    ** 2

    define ismultiple(x, y);
        erase(x // y) == 0
    enddefine;
