i currently have a batch file that will pull the system date and display it in the MMDDYYYY format. i then use this piece of code in various activities such as renaming files, makeing directories, etc.

does anyone have any idea how to pull 'yesterdays' date? or any other ideas how to change what i currently have. this is my current code, im running it off a win 98 machine.

:: Get current date into %date% variable without separators
@echo off
echo @PROMPT SET DATE=$D$_> %temp%.\temp.bat
%comspec% /c %temp%.\temp.bat > %temp%.\temp2.bat
echo.> %temp%.\temp.bat
for %%? in (e111''3B e114''3B w q) do echo %%?>> %temp%.\temp.bat
DEBUG %temp%.\temp2.bat nul
call %temp%.\temp2.bat
:: Next line defines date format. The values generally are:
:: %%1=Week day %%2=Month %%3=Date %%4=Year (4 digits)
:: Those could change, depending mainly on the COUNTRY
:: command (from config.sys).
echo SET DAY=%%3> %temp%.\temp.bat
call %temp%.\temp.bat;%date%
echo %day%
echo SET DATE=%%2%%3%%4> %temp%.\temp.bat
call %temp%.\temp.bat;%date%
for %%? in (temp.bat temp2.bat) do if exist %temp%.\%%? del %temp%.\%%?
echo %date%

That script will get today's and yesterday's date into the variables %TODAY% and %YESTERDAY%. The format is MM/DD/YYYY, but that can be changed (read commented lines).

That script is only for NT systems. In order to do such a thing in Win9x, I would store today's date to be used tomorrow, instead of calculating yesterday's date.

yes i had found that script earlier, but i dont have win nt on my computer. everything i have tried for calculating yesterdays date has not turned out well. i can get todays date with no trouble, how might i store the date from the variable and then retrieve it back into a variable when it is again needed?
