    {

    String mapleArgs[];

    Engine engine;

    Expseq e;

    mapleArgs = new String[1];

    mapleArgs[0] = "java";

    engine = new Engine( mapleArgs, new EngineCallBacksDefault(),

        null, null );

    e = (Expseq)engine.evaluate( "1,2,3:" );

    System.out.println( e.length() );

    e = engine.newExpseq( 4 );

    e.assign( 1, engine.newNumeric( 1 ) );

    e.assign( 2, engine.newNumeric( 2 ) );

    e.assign( 3, engine.newNumeric( 3 ) );

    e.assign( 4, engine.newNumeric( 4 ) );

    e = (Expseq)e.unique();

    System.out.println( e.length() );

    e = (Expseq)engine.evaluate( "seq( i, i=1..100 ):" );

    System.out.println( e.length() );

    }
