Reference category in competing risk analysis

[nmas]

Hi,
I am undertaking competing risk analysis. One of the explanatory variables called "Recode_changed" is categorical with 11 levels/ categories (ranging from 1 to 11). SAS by default chooses 11 as reference. Does anyone know how to change this to for example 2 or 3? 

My code:

proc phreg data=LIB.'COMPETING RISK SET UP 7 CAT1S'n;
class sexd Recode_changed / param=ref;
model Follow_time*Status(0)=sexd Recode_changed age Decrease_med_TOTAL
Increase_med_TOTAL / eventcode=1;
run;

Thanks!

See this example in the doc.

class sexd Recode_changed(ref='2') / param=ref;
