DOPTNAME(directory-id,nval) |
is a numeric variable that specifies the identifier that was assigned when the directory was opened by the DOPEN function.
is a numeric constant, variable, or expression that specifies the sequence number of the option.

Operating Environment Information: The number, names, and nature of the directory information varies between operating environments. The number of options that are available for a directory varies depending on the operating environment. For details, see the SAS documentation for your operating environment.

This example opens the directory with the fileref MYDIR, retrieves all system-dependent directory information items, writes them to the SAS log, and closes the directory:
%let filrf=mydir; %let rc=%sysfunc(filename(filrf,physical-name)); %let did=%sysfunc(dopen(&filrf)); %let infocnt=%sysfunc(doptnum(&did)); %do j=1 %to &infocnt; %let opt=%sysfunc(doptname(&did,&j)); %put Directory information=&opt; %end; %let rc=%sysfunc(dclose(&did));
This example creates a data set that contains the name and value of each directory information item:
data diropts; length optname $ 12 optval $ 40; keep optname optval; rc=filename("mydir","physical-name"); did=dopen("mydir"); numopts=doptnum(did); do i=1 to numopts; optname=doptname(did,i); optval=dinfo(did,optname); output; end; run;
