New variable assignment not working?

[jiangmi]

Hi, All,

I am a little confused that variable age2 is not showing up.

It will work if      'age2=age*1;'     was put behind     'set have;'   .

Can somebody tell me why?

Thanks.

Joe

data have;

input sex$ age;

datalines;

F 14

M 15

;

data male female;

set have;

if sex='M' then output male;

else if sex='F' then output female;

age2=age*1;

run;

Order of operations. Your output statement is before the calculation, so when SAS writes out the observation it hasn't been calculated yet.  

You do get the age2 variable but it is all missing.

Hi ,

You can use the below set of code ,by moving the age2 before the output statements.

data have;

input sex$ age;

datalines;

F 14

M 15

;

data male female;

set have;

age2=age*1;

if sex='M' then output male;

else if sex='F' then output female;

run;
