Getting a for loop working

I'm trying to split apart the system path variable with batch. This is what I have:

@echo off
setlocal EnableDelayedExpansion
set npath=%path%
set i=0
echo %npath% > temp
for /f "delims=;" %%a in (temp) do (
    echo [!i!]: %%a
    set /a i=!i!+1
)

When it runs, however, it only runs the loop a single time. Instead of my expected output, a list of the directories in PATH, it just outputs a single one:

stupid lazy batch

What's happening? Am I doing something wrong? I've tried using path as a string, I've tried changing the number of tokens, I've tried like everything. Do I just not understand how for loops work in batch?

try to iterate the items in the path with plain FOR loop (and you need to set quotes to prevent space collisions):

@echo off

setlocal enableDelayedExpansion
set "_path="!path:;=" "!""
rem echo %_path%
set i=0
for %%a in (%_path%) do (
    echo [!i!]: %%~a
    set /a i=!i!+1
)
endlocal
