| Does anyone have a ready made function ( or an algorythm ) for WinZip
and/or Unix-Z types of compression in APL please ?

If you want to unpack files packed by a proprietory tool I guess you'd
be best finding a way to call it or something similar from APL.
If you want to pack and unpack stuff yourself within APL using LZW
because you know it's good then John Scholes has one in the Dyalog
supplied ws "dfns" under the name of packZ with extensive notes.

| Thanks to everyone for the replies.
The "WinZip" API-connection ( AAsk ) was actually the sort of solution
that I was looking for.
PS:
.. I was only interested in "reading in" existing WinZip files and
extracting the content, rather than wanting to create such files
myself !

| You can easily call Java's zip tools from APL2.
