Implementation and code
Objective of this presentation is to demonstrate automating zipping process using advance SAS MACRO. I will discuss translating requirements into architectural design and SAS macro approach to get desired outcome

3. Requirement & Architectural Design
Pickup files based on dates modified from different folder and dump into zipped folder

4. Code PROC PRINTTO; RUN; %global FILE_NAME; %global zipped_folder_name;
%global numoflocation;
%global numofftozip;
%LET path = EXCEL_FILE_LOCATION;
%LET logPATH = LOG_FILE_LOCATION;
DATA _NULL_;
CALL SYMPUT('LOGTIME', STRIP(COMPRESS(PUT(DATE(),YYMMDD10.),'-'))||'_'||STRIP(COMPRESS(PUT(TIME(),TOD9.),':')) );
PROC PRINTTO LOG="&logPATH\SAS_LOG\zipp_&LOGTIME..LOG";
DATA INPUT_DATA;
CALL SYMPUT('FNAME','''' || 'DIR "'|| "&PATH"|| '" /B' || '''');
%PUT FNAME = &FNAME;

5. Code Continue… filename DIRLIST pipe &FNAME; %MACRO FIND_EXCEL_FILE;
%LET FILE_NAME = '';
%LET BOL_FILEFOUND = 0;
data dirlist ;
infile DIRLIST lrecl=200 truncover;
