You can run ARCHPR with command line parameters. The syntax is:
ARCHPR [switches] [zip/arj/ace/rar-filename]
or
ARCHPR [switches] [axr-filename]
The switches are separated with a "/" or "-". If the switch is followed by values (e.g., filename, starting password, etc.) containing special characters (space, semicolon, slash or dash), it must be enclosed in single or double quotes.
