Syntax

sysrc

contains the return code for the operation:

0	successful
0	not successful

Type: Numeric

fileref

is the fileref that was assigned to the external file to be deleted.

Type: Character

Details

You can use either the FILENAME statement or the FILENAME function in SCL to assign a fileref. Under some operating systems, you can also use system commands to assign filerefs.

Example

Generate a fileref for an external file and assign it to the variable FREF. Then call FDELETE to delete the file and call the FILENAME function again to deassign the fileref.

length fref $ 8;
fref =_blank_;
   /* Assign a fileref generated by the system */
   /* to the physical filename that is stored  */
   /* in the variable FNAME.                   */
 rc=filename(fref,fname);
if (rc=0) and (fexist(fref)) then
   rc=fdelete(fref);
rc=filename(fref,'');
