Details

DINFO returns the value of a system-dependent directory parameter. The available information varies according to the operating system. See the SAS documentation for your host operating system for information about system-dependent directory parameters.

Use DOPTNAME to determine the names of the available system-dependent directory information items. Use DOPTNUM to determine the number of directory information items available.

Example

Open the directory MYDIR, determine the number of directory information items available, and retrieve the value of the last item:

   /* Assign the fileref MYDIR to the */
   /* pathname stored in the variable */ 
   /* or entered in the DIRNAME field and open it.*/
   rc=filename('mydir',dirname);
did=dopen('mydir');
numopts=doptnum(did);
foption=doptname(did,numopts);
charval=dinfo(did,foption);
rc=dclose(did);
