Functions and CALL Routines |
Returns the number of information items that are available for
a directory.
-
directory-id
-
is a numeric variable that specifies the
identifier that was assigned when the directory was opened by the DOPEN function.
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 retrieves the number of system-dependent directory
information items that are available for the directory MYDIR and closes the
directory:
%let filrf=mydir;
%let rc=%sysfunc(filename(filrf,physical-name));
%let did=%sysfunc(dopen(&filrf));
%let infocnt=%sysfunc(doptnum(&did));
%let rc=%sysfunc(dclose(&did));
This example creates a data set that retrieves the number of system-dependent
information items that are available for the MYDIR directory:
data _null_;
rc=filename("mydir","physical-name");
did=dopen("mydir");
infocnt=doptnum(did);
rc=dclose(did);
run;
