How to Divide two rows?

[Phoenix8527]

Here is my dataset. I want to calculate Percentage as Y/(Y+N) using Count number for both NBUS and Season. Anyone know how to get the results?  Thanks a lot

Status	Tenure	Count
N	NBUS	543
N	Season	1099
Y	NBUS	276
Y	Season	264

data have;

input Status $ Tenure $ Count;

cards;

N NBUS 543

N Season 1099

Y NBUS 276

Y Season 264

run;

proc sql;

create table want as

select status, tenure, count, count/sum(count) as Pct

from have;

quit;

The Final result I want to get is 276/(276+543) for NBUS, 264/(264+1099) for Season.

proc sql;

create table want as

select status, tenure, count, count/sum(count) as Pct

from have

group by tenure;

quit;

[VD · Accepted solution]

proc sql;

     create table want1 as select

     status, tenure, count, sum(count) as sum

     from have

     group by tenure;

quit;

proc sql;

     create table want2 as select

     status, tenure, count/sum*100 as percent

      from want1

      where status='Y';

quit;

Times 100.
