Dear,

I am trying to create a variable from data1. But I am getting the output value for last OBS only. Why. Please help. Thanks.

my code:

data one;
set data1;
if trta='75 mg' then trt='A';
if trta='150 mg' then trt='B';
if trta='300 mg' then trt='C';
if trta='TOTAL' then trt='D';
run;

data1;

ns        trta

50        100 mg

60         25 mg

70         125 mg

180        Total

my code:

data one;
set data1;
if trta='100 mg' then trt='A';
if trta='25 mg' then trt='B';
if trta='125 mg' then trt='C';
if trta='TOTAL' then trt='D';
run;

ouput getting:

ns        trta                             trt
