For a regular variable both %'s are needed:

C:\>set ab=foo
C:\>echo %ab
%ab

FOR loop variables however seem impossible to escape, so one must be
careful to avoid using a sequence that matches a used variable.

C:\>for %a in (*) do @echo %ab
FOO.TXTb

C:\>for %a in (*) do @echo %%ab
%FOO.TXTb

C:\>for %a in (*) do @echo ^%ab
FOO.TXTb

C:\>for %a in (*) do @echo "%ab"
"FOO.TXTb"

C:\>for %a in (*) do @echo ^%^ab
FOO.TXTb

C:\>for %a in (*) do @echo ^%^%^ab
%FOO.TXTb

C:\>for %a in (*) do @echo ^^%ab
^FOO.TXTb

C:\>for %a in (*) do @echo ^%^^%ab
%^FOO.TXTb

C:\>for %a in (*) do @echo "^%^^%ab"
"^%^^FOO.TXTb"
