Hi there,

This might be too long, please bear with me.

Basically I want to use proc report because I have to present both detailed rows and some summary result. Unfortunately, I need "median" which can only be calculated by proc univariate (yes, this is for SAS 6.12), steps 2-6 is to manipulate data, so that it has necessary vars for proc report compute block.

I would like to summarize by study and also for all studies at the end of the list.

data xx; input study $ sex $ age ncrs desc $; cards; B F 67 8 stst B F 34 10 sdfsaf B M 55 7 sdryts B M 73 7 werwer B M 46 9 sdgsf A M 45 3 abcd A M 65 4 bdrf A F 46 3 lsdfsd A F 67 5 sdfas ;

proc sort; by study;

proc univariate noprint data=xx; by study; var age ncrs; output out=temp n=n1 median=m1 m2;

proc univariate noprint data=xx; var age ncrs; output out=temp1 n=on1 median=om1 om2;

data xx; merge xx temp; by study;

proc sql; create table xx as select xx.*, temp1.* from xx, temp1 order by study ;

options nocenter; proc report nowd headline; column on1 om1 om2 n1 m1 m2 study sex age ncrs desc; define study / width=5 order; define sex / width=3 order; define age / width=3; define ncrs / width=5; define n1/noprint order; define m1/noprint order; define m2/noprint order; define on1/noprint order; define om1/noprint order; define om2/noprint order; compute after study; line ' '; line 'N=' n1 3.; line 'Median age=' m1 5.1; line 'Median CRS=' m2 5.1; line ' '; endcomp; compute after; line ' '; line 'Total N=' on1 3.; line 'Overall Median age=' om1 5.1; line 'Overall Median CRS=' om2 5.1; line ' '; endcomp; run;

----------------------------- study sex age ncrs desc ------------------------------------- A F 46 3 lsdfsd 67 5 sdfas M 65 4 bdrf 45 3 abcd

N= 4 Median age= 55.5 Median CRS= 3.5

B F 34 10 sdfsaf 67 8 stst M 55 7 sdryts 46 9 sdgsf 73 7 werwer

N= 5 Median age= 55.0 Median CRS= 8.0

Total N= . Overall Median age= . Overall Median CRS= .

Now my question is why the second compute block dose not work?

Thanks.
