Formatting a macro for use in file extension (proc import and proc export)

[JJ7]

Hi all!

For most of my reports I am able to just use &eom. in my file extensions, but for a project I am working on, I need to be able to import a file based on its file extension of the previous Wednesdays date in DDMMYYN8. format. I have looked through the other questions and found the following, but when I use it, it exports with the SAS date format and not the format I want, and I cant seem to figure out how to format it.

data _null_;
today="&SYSDATE9"d;
lastwk=intnx('week', today, -1);
lastwed=intnx('week.4', lastwk , 1);
run;

data _null_;

lastWed = intnx('week', today(), 0, 'b') - 4;

call symputx('lastWed', put(lastWed, ddmmyyn8.));

run;

%put &lastWed.;
