How to order several variables?

RavenWu — Sun, 24 Jul 2016 09:59:17 GMT

The following is my codes, and I want to order id cash ticket (low- high) and quantity (high-low), but I found that I can't order all of

this variables at the same time as I want. For example, if I want to order id from low to high, then I can't order the cash from low to high anymore since the orders of this two variables are conflict, and that is logical.

DATA HAVE;
INPUT  id 4. ticket 3. quantity 3. cash 3.;

DATALINES  ; 
3000 15	1 92
3002 1 	0 86
3002 24	0 86
3009 3  5 91
;
RUN;
PROC SORT DATA=HAVE OUT=WANT;
BY id cash ticket  DESCENDING quantity;
RUN;

output:

I want to confirm that Is it true that it is impossible to order several variables at the same time if their orders are conflict?

I am not sure, maybe there is other way that I can't think up.

I'm not sure what you are expecting?
What is your desired output?
Tables are two dimensional so you can't have several sort orders at the same time.
By specifying several by variables you are specifying the order of that variable within the the previous by variable value.

Off topic (combination SAS/R solution -casino slot machine like problem)

see

You may be able to spin both columns independently with a SAS or WPS hash?

Also probably easy with SAS/IML.
