Yes I have a similar sort of text file
text file 1:
001DATA...
002DATA...
RSSDATA...
001DATA...
002DATA...
text file 2:
001DATA...
002DATA...
001DATA...
002DATA...
Here as per the data if I dont find the value of a variable to be RSS then dont need to read the text file.
One way to code such a test is to take advantage of the CANCEL option on the RUN statement. So first create an empty macro variable and then while reading the first file conditionally set the macro variable to contain the keyword CANCEL. Then reference the macro variable in the second data step that reads the second data file.
%let run_cancel=;
data _null_;
infile 'file1' ;
input;
if _infile_=: 'RSS' then do;
call symputx('run_cancel','cancel');
stop;
end;
run;
data want ;
infile 'file2' ;
input ....... ;
run &run_cancel ;
yup this is what I was looking for tom. thanks a lot ...
