special characters ≥ and ≤ and format

fengyuwuzu — Tue, 03 May 2016 03:26:33 GMT

I have special characters in my data, ≥ and ≤. without any format, I can produce the freq table as below:

But I want to order the age groups, so they are in order, and tried to use the following code to create a format. However, the format does not work.

I found a old post in 2013 mentioning running SAS in unicode mode, but I do not know how to run SAS in unicode mode. Can nay one help? Thank you.

PROC FORMAT;
   VALUE $ typefmt 
        1 = '(*ESC*){unicode '"2264"x} 20'
        2 = '21-25 '
        3 = '26-30 ' 
	4 = '(*ESC*){unicode "2265"x} 31'
;
quit;
proc freq data=new_vvnv;
tables age_group*status /nocol  ;
format age_group $typefmt.;
run;

I'm not following.
The freq output looks like the code you are supplying?
And from this code it seems that your data contains 1, 2, 3 and 4 - not any special characters...?

Hi: Since you did not provide data to test with I made some fake data from SASHELP.CLASS. But using ORDER=DATA (after I'd sorted the file) worked for me to put the AGE_GROUP in order.

I got the following error:

Please remove the single quote in

... unicode '"2264"x ...

I used the following code, now format is okay (thanks for pointing out a single quote in original code), but the sort does not work. After sort, 21-25 is still the first age group.

PROC FORMAT;
   VALUE $ typefmt 
        1 = '(*ESC*){unicode "2264"x} 20 '
        2 = '21-25 '
        3 = '26-30 ' 
	4 = '(*ESC*){unicode "2265"x} 31 '
;
quit;

proc sort data=new_vvnv;
format age_group $typefmt.;
by age_group age;
run;


proc freq data=new_vvnv order=data;
tables age_group*status /nocol  ;
format age_group $typefmt.;
run;

I think, you could simply sort

by age;

rather than by age_group age to achieve the desired result.

Still, it would be interesting to find out why sorting by AGE_GROUP, which should contain values '1', '2', '3' and '4', fails to bring '1' to the top. (PROC SORT always sorts by unformatted values.) My next step would be a closer look at the unformatted values of AGE_GROUP.

yes simply sort by age works. Thanks
