Under Win32, arj uses OEM codepage by default. The "-hy" option sets arj to use the ANSI
codepage which is the Windows graphical environment default. arj/Win32 self-extracting
archives should be built using the "-hy" option.

To ensure compatibility with previous versions of arj, the "-2d" parameter has to be
specified when archiving under UNIX.


Yes yes

No no

Quit abort out of arj

Always always assume yes for current type of query

Skip always assume no for current type of query

Global always assume yes for all queries except diskette volume prompts

prompt for and execute one system command

If the first two characters of an arj comment are "))" in a self-extractor, then the self-
extractor will accept the appended line as its command line.

")) -o" will force the self-extractor to overwrite existing files.
