Thank you, Martin!

These information is very useful and helpful. I have another issue below, could you please help?

When below code is run in Linux, a warning below is shown in Log. I thought to delete the file templat.sas7bitm to avoid this warning to appear in log. But the warning appears first, then the templat.sas7bitm is deleted. So I think to suppress this warning. I googled and do not find a way to suppress this warning. Do you have a thought about suppressing this warning?

%if %bquote(%upcase(&sysscpl)) = LINUX %then %do;
proc datasets library=sasuser nolist;
delete templat(memtype=itemstor);
run;
%end;

WARNING: SASUSER.TEMPLAT is not a template store! It will be ignored.
