In Windows batch scripting, how are loop variables denoted when used inside a script?

Explanation:
Loop variables in Windows batch files use double percent signs. In a batch script, the FOR loop variable must be written with two percent characters (for example, FOR %%F IN (*.txt) DO echo %%F). The double percent avoids confusion with command-line parameter expansion, which uses a single percent when typing directly at the prompt (FOR %F IN (*.txt) DO echo %F). Other symbols like $ or @ aren’t used to denote FOR loop variables in batch scripts.
