“Batfiles: The DOS batch programming handbook”
“Using MS-Dos7 Commands”
These extensive works are unavailable at this time. I plan to put them back on-line, but I can’t say exactly when. Please note: When these works do come back on-line, they will appear on a different domain, so if you are interested, please bookmark the following purls and check periodically.
Alas, I do not wish you to go emptyhanded. At the link below is a fun batch game that you will likely return to again and again. I suggest you download the batch because it is more reliable than copy and paste.
