Resetting multiple variables at once

#1 Post by batchcc » 09 Nov 2016 14:57

I have a batch file with a large amount of variables now rather than adding this to the beginning of the file is there an easy way to resset all the variables?

Code: Select all

set var1=
set var2=
set var3=
set var4=
set var5=
set var6=
set var7=
set var8=
...

Thank you!

You have to undefine them separately but you could use loops.

Code: Select all

for /l %%i in (1 1 8) do set "var%%i="

or

Code: Select all

for /f "delims==" %%i in ('set var') do set "%%i="

or

Code: Select all

for %%i in (a_variable another_variable another_different_variable) do set "%%i="

The only time you don't need individual SET statements is when you are initializing a series of numeric values. For example, you could initialize four variables to 0:

Code: Select all

set /a var1=var2=var3=var4=0
