How to get rows when condition met

[ Edited ]

Detail question
I have a data set with A,B,C,D... attributes so in C I have {ACE,ALM,BDS} .

so when ever I got "ACE" in C then the output has to get  15 lines from the condition it has met and it has to go until the end of the row.

Can any one provide me the codeUntitled.png

I'm not 100% this is what you are looking for but here is a solution for how I translated your question:

 

data have;
infile cards dsd ;
input a$ b$ c$ d$;
cards;
,one,,
,two,,
ACE,,,
,two,,
,three,,
,four,,
,five,,
,six,,
,seven,,
,eight,,
,nine,,
,ten,,
,eleven,,
,twelve,,
,thirteen,,
,fourteen,,
,fifteen,,
,sixteen,,
ACE,,,
,two,,
,three,,
;
run;

data want(drop=count ace_count);
set have;
count + 1;
if a = 'ACE' then count = 1;
retain ace_count;
if a = 'ACE' then ace_count = 1;
if count > 15 then ace_count = .;
if 1 <= count <= 15 and ace_count = 1 then output;
run;

You are welcome Smiley Happy I would google SAS Retain and look around. There is a ton of information. I prefer anything that is from a sas users group. There's a lot of information available from classes too: https://onlinecourses.science.psu.edu/stat481/node/36
