Hello,

I just try to concatenate the following variables:
@echo off
FOR /F "tokens=1,2,3 delims=." %%a in ("%date%") do set yy=%%c& set mm=%%b & set dd=%%a
set /a lastyear=%yy%-1
set output=IS_%lastyear%

echo %output%

_________________________
Output:
IS_

Output should be IS_2014

Can somebody help me?

Fixed Code:

Code: Select all

@echo off
FOR /F "tokens=2,3,4 delims=/" %%a in ("%date: =/%") do set yy=%%c& set mm=%%b & set dd=%%a
set /a lastyear=%yy%-1
set output=IS_%lastyear%
echo %output%

Output:

Code: Select all

IS_2014

Have a look in the %date% variable:

Code: Select all

>echo %date%
Wed 12/16/2015

The delimiters here are [space] and Slashes. I used %date: =/% in IN so that the delimiter will only be slashes.

Code: Select all

>echo %date: =/%
Wed/12/16/2015

This is simpler, but works as well:

Code: Select all

FOR /F "tokens=2,3,4 delims=/ " %%a in ("%date%") do set yy=%%c& set mm=%%b & set dd=%%a

There are spaces there which will be a problem.
