data:

 

 

IDab
1102
120014.4

want:

 

IDabc (flag)
11020
120014.40
140050

So,  variable b has same value 5 in rows 3 and 4. I need to flag first value (row 3)as 0 and subseqent rows containing value 5 as 1.

 

Thank you.

How about this then:

proc sort data=have;
   by id b;
run;
data want;
   set have;
   by id b;
   c = 0;
   if not first.b and b=5 then c=1;
run;

This is my 2 cents. Depending on what you'd like to do with variable a your final version can differ. But the use of first. will be my recommendation.

proc sort data=have;
   by id b;
run;
data want;
   set have;
   by id b;
   if first.b then c=0;
   else c=1;
run;

You code works but I need to flag only  one numeric value 5.  For instance, if there are duplicate 8 values , there is no need to flag
