Listers, the interface through which you manipulate files in Opus v5, are
the heart of the system, so it makes sense that we should know how to open
and close the things :)
Whenever you successfully open a lister, a handle for that particular
lister will be returned in the RESULT variable. This handle will be required
if you need to do any further operations on that lister, for example, close
it.
lister new
This is the only ARexx command that can open a lister, and it will let you
do it in any mode, position, path, with any toolbar, iconified, invisible and
standing on your head, (see the all new dopus user position command).
lister close
This command can close a single lister or it can close them all.
lister iconify
If you want to make a lot of space available on screen fast without closing
any listers, lister iconify is the command for you.
lister read
This lets you read another path into the lister.
lister copy
The lister copy command lets you quickly copy the contents of one lister
to another.
lister wait
Some lister operations can take a while, for example, reading in a
directory with hundreds of files. This command will force the script to wait
until the lister is again ready to accept commands, ensuring that none are
lost.
