Question

I have a data that looks like this

Thanks in advance

Answer 1

It is not entirely clear what you are wanting to do, but when you want to look across variables in a data set Arrays are your best friend. After reviewing the documentation, look for any of the great papers posted on how to use Arrays.
Update your question for a more specific response.

Answer 2

Please type out your data in the future, ideally as shown below. This shows how you can capture a streak.
data have;
input Name A0-A10 MAX;
cards;
1 10 9 12 12 12 12 12 11 12 12 9 12
2 45 67 23 67 9 45 67 67 67 67 67 67
3 12 14 1 16 14 16 16 16 16 16 16 16
4 14 56 7 68 94 35 67 342 252 253 35 342
;
;
;
run;
data want;
set have;
*declare array to loop;
array A(0:10) A0-A10;
*use a counter to keep track of consecutive values;
counter=0;
*use a variable to keep track of the largest streak;
max_streak=0;
*loop start;
do i=0 to 10;
*if value matches maximum increase the counter;
if A(i)=max then
counter+1;
*if streak is larger than the largest streak replace the largest streak;
if counter>max_streak then
max_streak=counter;
*set streak back to 0 if value does not match maximum;
if A(i) ne max then
counter=0;
end;
run;

data have;
input Name A0-A10 MAX;
datalines;
1 10 9 12 12 12 12 12 11 12 12 9 12
2 45 67 23 67 9 45 67 67 67 67 67 67
3 12 14 1 16 14 16 16 16 16 16 16 16
4 14 56 7 68 94 35 67 342 252 253 35 342
;
data want(drop = c);
set have;
array a a:;
i = 0; c = 0;
do over a;
if a = max then c + 1;
if c > i then i = c;
if a ne max then c = 0;
end;
run;
