Purpose ======= The CD command that comes with MS or PC DOS has three flaws: 1. It does not set the ERRORLEVEL for Invalid directories. 2. It fails when there is a trailing backslash on the name. 3. You cannot hide its error messages with >NUL: redirection. 4. It won't also change the drive for you in one step. CDD! acts just like CD except that it fixes these four problems. CDD! is slower since it is must be loaded each time, whereas CD is internal to DOS. It is similar to the 4DOS command CDD. Samples of Use ============== CDD! behaves just like the normal 4DOS CDD command except that it sets ERRORLEVEL to 1 if it fails because the directory requested does not exist. CDD! C:\MYDIR\MYSUBDIR IF ERRORLEVEL 1 ECHO missing directory CD \MYDIR CDD! SUBDIR IF ERRORLEVEL 1 ECHO missing directory CDD! \MYDIR\MYSUBDIR\ IF ERRORLEVEL 1 ECHO missing directory CDD! .. IF ERRORLEVEL 1 ECHO already at the root CDD! D:\ REM changes the current directory on D: to the root CDD! D: REM displays the current directory on D: CDD! REM displays the current directory.
