How to set a password for multiple datasets

[mkb321]

I have several hundred datasets which all need to have password protection added (the same password for all datasets). The naming convention used is data_yyyyMMMdd with the dates increasing weekly (example: data_2022mar13, data_2022mar20).

Is there a way to modify all datasets in the dataset procedure?   I looked at the example date %do loop here: https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.5/mcrolref/n01vuhy8h909xgn16p0x6rddpoj9.htm

however SAS doesn't seem to recognize the yyyyMMMdd date format.

Thanks in advance!

How about this? Run to see how it works and complete as required.

ods output members=MEMBERS;
proc datasets lib=WORK ;
run;
ods output close;

data _null_;
  set MEMBERS;
  where MEMTYPE='DATA';
  if _N_=1 then call execute('proc datasets lib=WORK;');
  call execute('modify '||NAME||';');
run;
run;

If these tables are all in a single or only a few libraries then another option could be the use of metadata bound libraries.
