How would I do a checksum of a SAS program code file

[megp]

Hello,

I would like to do a checksum at the end of my SAS program in order to be able to identify if there has been any changes to my code since the last time I worked on it. 

Has anyone done this before and would be able to provide some help? Or have a better solution for what I would like to do?

Thank you

If you're using SAS EG or SAS Studio you can link your programs to a version control software or repository.

Thanks for the suggestion, however I want to avoid having to use a version control software or repository.

Finally, i used the following solution to get the checksum of the current program I am running:

data checksum;
title "Checksum";
filename fn pipe "CertUtil -hashfile %sysget(SAS_EXECFILEPATH) MD5";
infile fn;
input;
Hash_Info = _infile_;
run;
proc print data=checksum NOOBS;
run;

Thanks for taking the time to help!
