I've been programming in dozens of languages for 20 years but I could never understand how "FOR" work in windows cmd shell batch file, no matter how hard I tried. I read

http://www.amazon.com/Windows-Administration-Command-Line-Vista/dp/0470046163/ref=sr_1_1?ie=UTF8&s=books&qid=1241362727&sr=8-1

and several other articles on the internet but still confuse and cannot accomplish anything.

Can anybody give me a concise explaination on how "FOR" works in general ?

For a little more specific question, how can I iterate through each path in %PATH% variable ? I've tried with 

rem showpathenv.bat
for /f "delims=;" %%g in ("%PATH%") do echo %%g

That'd show only the first path, not all of them. Why ? What I do wrong ?
