FINFO Output for Disk Files

The following example and output illustrate the use of FINFO and the other file access functions for disk files:

data _null_;
   length opt $100 optval $100;
   rc=FILENAME('myfile', 'finfo list *'); /* allocate file   */
   fid = FOPEN('myfile');                 /* open file       */
   infocnt=FOPTNUM(fid);  /* get number of information items */

   /* Retrieve information items and print to log*/
   put @1 'Information for a File:';
   do j=1 to infocnt ;
      opt = FOPTNAME(fid,j);
      optval  = FINFO(fid,upcase(opt));
      put @1 opt @20 optval;
   end;

   rc = FCLOSE(fid);                      /* close file      */
   rc = FILENAME('myfile');               /* deallocate file */

   infocnt=FOPTNUM(fid);       /* get number of information items */

   /* retrieve information items and print to log*/
   put @1 'Information for a File:';
   do j=1 to infocnt;
      opt = FOPTNAME(fid,j);
      optval  = FINFO(fid,upcase(opt));
      put @1 opt @20 optval;
   end;

   rc = FCLOSE(fid);                       /* close file          */
   rc = FILENAME('myfile');                /* deallocate the file */
