Order of variables in result



Hi,

I have a question about simplification system. Usually Maxima does sorting
of all variable-names in result of processing.

For example, for input  x+y   we will have output  y+x.

Is it possible to suppress this behavior of Maxima? Is it necessary to do
changes in the source code of simplification system?

Thank you for attention to my message.

Best regards,
