Hello,   I have a large data-set that I had to split into 360 smaller sets by value (byval), I need to export the smaller sets into individuals excel files .csv and im having trouble coming up with the proc export. Here is what i'm doing:       Proc sort data = HQ.private; by hospital_system; run;   %macro break(byval);       data &byval;       set HQ.private(where=(hospital_system="&byval"));       run; %mend;   Data _Null_; set HQ.private; by hospital_system; if first.hospital_system then       call execute(%nrstr('%break('||trim(hospital_system)||')')); run;   proc export DATA=work.pih DBMS=EXCEL outfile="C:\Users\ekala1\Documents\HQAF\pih.xls" replace; run;   When I run my proc export, it does not execute. Any help or advice would be greatly appreciated.   Thank you,   Ella ... View more
