Here's the a very simple way.

RETAIN holds the value across the rows. 

FIRST.SEX is one on the first record of every Sex grouping and 0 otherwise. 

 

 

proc sort data=sashelp.class out=class;
by sex;
run;

data want;
set class;
by sex;
retain count;
if first.sex then count=1;
else if count=7 then count=1;
else count+1;
run;
