Hey dude/dudette.. Check out this previous EE posting..

http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/MS_DOS/Q_21356348.html

Remember that if you change the environment in a batch file, the changes only exists for that batch file and files called from that file.. Once the file terminates, the changes are gone..

In a batch file:

for /f "tokens=1 delims=.:/-, " %%u in ('date /t') do set dayname=%%u

If in a dosbox (not a batch file) change %%u in %u

Depending on what you are trying to do, I have a small C utility I wrote long ago for DOS, that will rename any file to the 3-letter day of week without changing the extension - we use this for renaming ZIP & 7zip archives on our clients' servers prior to uploading for a rolling 7-day offsite backup.. I'll post the source code if you want it..

From the link above this code works !!!!!

rem Create the date and time elements.
For /f "tokens=1-7 delims=.:/-, " %%i in ('echo exit^|command /K prompt $D $T ') do (
For /f "tokens=2-4 delims=/-,() skip=1" %%a in ('echo.^|date') do (
set dow=%%i
set %%a=%%j
set %%b=%%k
set %%c=%%l
set hh=%%m
set min=%%n
set ss=%%o
)
)
echo off
cls
Echo %DOW%


Can somone optimize it for me as I only need the DOW
I know to delete the "SET" but is the other bit optimized ??


Thanks in advance.

Reduced version. It is not very sophisticated, as it has to use command.com, which switches in 16bit DOS mode, but if you like it ...

rem Create the date and time elements.
For /f "tokens=1-7 delims=.:/-, " %%i in ('echo exit^|command /K prompt $D $T ') do ^
For /f "tokens=2-4 delims=/-,() skip=1" %%a in ('echo.^|date') do set dow=%%i
echo off
cls
Echo %DOW%

Have you considered either the VBS or datex solutions in http://www.experts-exchange.com/Q_24447856.html yet?

This is about as optimized as I can get it

@echo off

For /f "tokens=1-1 delims=.:/-, " %%i in ('echo exit^|command /K prompt $d ') do ^
For /f "tokens=2-4 delims=/-,() skip=1" %%a in ('echo.^|date') do set dow=%%i

Echo %DOW%

My manager has just shown me up by writing this:

What do you think of that....
for /F "tokens=1,2,3 delims=/- " %%a in ("%DATE%") do (
set /A DD=%%a
set /A MM=%%b
set /A YY=%%c
)
 
 
SET /A LEAPDAYS=((%YY%-2000)/4)
 
SET /A YEARDAYS=((%YY%-2000)*365)+%LEAPDAYS%
 
IF %MM% == 1 SET /A MONTHDAYS=0
IF %MM% == 2 SET /A MONTHDAYS=31
IF %MM% == 3 SET /A MONTHDAYS=59
IF %MM% == 4 SET /A MONTHDAYS=90
IF %MM% == 5 SET /A MONTHDAYS=120
IF %MM% == 6 SET /A MONTHDAYS=151
IF %MM% == 7 SET /A MONTHDAYS=181
IF %MM% == 8 SET /A MONTHDAYS=212
IF %MM% == 9 SET /A MONTHDAYS=243
IF %MM% == 10 SET /A MONTHDAYS=273
IF %MM% == 11 SET /A MONTHDAYS=304
IF %MM% == 12 SET /A MONTHDAYS=334
 
 
SET /A TOTALDAYS=(%DD%+%MONTHDAYS%+%YEARDAYS%)
 
SET /A NOWEEKS=(%TOTALDAYS%/7)
 
SET /A DAYNUMBER=(%TOTALDAYS%-(%NOWEEKS%*7))
 
 
IF %DAYNUMBER% == 1 SET DATNAME=Sat
IF %DAYNUMBER% == 2 SET DATNAME=Sun
IF %DAYNUMBER% == 3 SET DATNAME=Mon
IF %DAYNUMBER% == 4 SET DATNAME=Tue
IF %DAYNUMBER% == 5 SET DAYNAME=Wed
