In constructions such as internal variables and variable functions, it should
always be a single percent sign; double percent signs will not work correctly. 
For environment variables and FOR-loop indices, you can use either single or
double percent signs, whether you're in a batch file or at the prompt.

My suggestion would be to always using single percent signs for clarity, unless
compatibility with legacy shells is an issue.
