A variable, for example %cdrom%: it can take you to the CDROM drive letter (you have to set it first)....

% is generally used in DOS commands as the marker for defining variables.
What is enclosed in % is generally a variable name.
Also, in batch processing, it is generally used as a formal parameter, together with shift (the displacement command). For details, you can look at posts about batch processing. Or look at the article below:
