一个内存数据库的源代码这是服务器端还有客户端

var b1 := bat(oid,str);
b1.reverse().sort().reverse().print();
b1.access(BAT_WRITE);
b1.reverse().sort().reverse().print();

var b2 := bat(void,str);
b2.seqbase(oid(10));
b2.reverse().sort().reverse().print();
b2.access(BAT_WRITE);
b2.reverse().sort().reverse().print();

var b3 := mirror(b2);
b3.print();

var b4 := b3.reverse().join(b2);
b4.print();
# next line produced an incorrect error 
# ERROR: CMDsort: returned BAT has unexpected head.
b4.reverse().sort().reverse().print();

#mini mil example

var b2 := bat(void,str);
b2.seqbase(oid(10));
var b3 := mirror(b2);
var b4 := b3.reverse().join(b2);
# next line produced an incorrect error

b4.reverse().sort().reverse().print();
