Loop over a list items in a batch script

I am trying to check if a set of directory exists or not. I am using a batch script.

I use "for" loop to loop over the list of the directories and checks if this directory exist or not:

set list=%HOME%\bin ^
%HOME%\tmp

for %%A in (%list%) do (
    if not exist %%A (
       echo %%A
    )
)

The problem is that I get an error: 'C:\mn\home\bin' is not recognized as an internal or external command, operable program or a batch file.

How to make the for loop avoid executing the items of the list?

Thanks

Put the list items in one line,
if they might contain spaces enclose in double quotes: set list="%HOME%\bin" "%HOME%\tmp"
separate items by space, comma, semicolon, tab or equal sign.

@Echo off
Set "Home=C:\mn\home"
set list="%HOME%\bin\",^
 "%HOME%\tmp\"

for %%A in (%list%) do (
    if not exist "%%~A" (
       echo doesn't exist %%A
    )
)

Sample output:

> SO_5053242.cmd
doesn't exist "C:\mn\home\bin\"
doesn't exist "C:\mn\home\tmp\"

It might be easier to put your items into the for directly:

@Echo off
Set "Home=C:\mn\home"

for %%A in (
"%HOME%\bin\"
"%HOME%\tmp\"
"%HOME%\blahtmp\"
) do (
    if not exist "%%~A" (
       echo doesn't exist %%A
    )
)
