Syntax

DINFO (directory-id,info-item)

directory-id: specifies the identifier that was assigned when the aggregate external files was opened (generally by the DOPEN function).
info-item: specifies the information item to be retrieved. Under CMS, the single valid value for info-item is 1, which returns the directory path associated with directory-id. If directory-id represents a single aggregate, the information returned by DINFO will be of the form 'pathname'. If directory-id represents a concatenated series of aggregates, the information returned by DINFO will be of the form ('pathname_1', ... 'pathname_n').

DINFO Output for SFS Directories

The following example and output illustrate the use of DINFO and the other directory access functions for SFS directories:

data _null_;                                      
   length opt $100 optval $100;                   
   rc=FILENAME('mydir', 'user1.');  /* allocate directory     */
   dirid = DOPEN('mydir');          /* open directory         */
   infocnt=DOPTNUM(dirid); /* get number of information items */
   
   /* retrieve information items and print to log*/
   put @1 'Information for an SFS Directory:';
   do j=1 to infocnt;
      opt = DOPTNAME(dirid,j);
      optval  = DINFO(dirid,upcase(opt));
      put @1 opt @20 optval;
      end ;

   rc = DCLOSE(dirid);            /* close the directory      */
   rc = FILENAME('mydir');        /* deallocate the directory */
run;

DINFO Output for Minidisks

The following example and output illustrate the use of DINFO and the other directory access functions for minidisks:

data _null_;
   length opt $100  optval $100;
   rc=FILENAME('mydir', 'A'); /* allocate directory */
   dirid = DOPEN('mydir'); /* open directory */
   infocnt=DOPTNUM(dirid); /* Get number of information items */

   /* Retrieve information items and print to log*/
   put @1 'Information for a Minidisk Directory:';
   do j=1 to infocnt;
      opt = DOPTNAME(dirid,j);
      optval  = DINFO(dirid,upcase(opt));
      put @1 opt @20 optval;
   end;
   
   rc = DCLOSE(dirid);  /* close the directory */
   rc = FILENAME('mydir'); /* deallocate the directory */
run;

DINFO Output for a Minidisk

Information for a Minidisk Directory: Directory A NOTE: DATA statement used: real time 0.18 seconds cpu time 0.18 seconds

DINFO Output for MACLIBs

The following example and output illustrate the use of DINFO and the other directory access functions for MACLIBs:

data _null_;
   length opt $100 optval $100;
   rc=FILENAME('mydir', 'dmsgpi maclib *'); /* allocate directory */
   dirid = DOPEN('mydir');                  /* open directory     */
   infocnt=DOPTNUM(dirid);     /* get number of information items */

/* retrieve information items and print to log*/
   put @1 'Information for a MACLIB Directory:';
   do j=1 to infocnt ;
      opt = DOPTNAME(dirid,j);
      optval  = DINFO(dirid,upcase(opt));
      put @1 opt @20 optval;                        
      end;

   rc = DCLOSE(dirid);                    /* close directory      */
   rc = FILENAME('mydir');                /* deallocate directory */
run;
