FDELETE(fileref | directory)

Required Arguments


is a character constant, variable, or expression that specifies the fileref that you assigned to the external file. You can assign filerefs by using the FILENAME statement or the FILENAME external file access function.

Restriction The fileref that you use with FDELETE cannot be a concatenation.
Windows specifics In some operating environments, you can specify a fileref that was assigned with an environment variable. You can also assign filerefs using system commands. For details, see the SAS documentation for your operating environment.


is a character constant, variable, or expression that specifies an empty directory that you want to delete.

Restriction You must have authorization to delete the directory.


FDELETE returns 0 if the operation was successful or ≠0 if it was not successful.


Example 1: Deleting an External File

This example generates a fileref for an external file in the variable FNAME. Then it calls FDELETE to delete the file and calls the FILENAME function again to deassign the fileref.
data _null_;
    if rc = 0 and fexist(fname) then

Example 2: Deleting a Directory

This example uses FDELETE to delete an empty directory to which you have write access. If the directory is not empty, the optional SYSMSG function returns an error message stating that SAS is unable to delete the file.
filename testdir 'physical-filename';
data _null_;
   put rc=;
   put msg=;
