You can change the environment variable DELDIR in OS/2 sessions to change the UNDELETE behaviour for a special session.
Examples:
REM *** OS/2 Batch file to change the DELDIR directory for one session SET DELDIR=C:\DELDIR1,512;D:\DELDIR_C,512; REM *** OS/2 Batch to disable DELDIR, delete some files and enable REM DELDIR again SETLOCAL SET DELDIR= DEL D:\TEMP\*.* ENDLOCAL REM *** OS/2 Batch to change the DELDIR directory, delete some files REM and restore the DELDIR directory afterwards SETLOCAL SET DELDIR=D:\MY_DELDIR,512 DEL D:\TEMP\*.* ENDLOCAL
Note: This method is also possible in DOS sessions.
