data want;

infile <fileref> ...;

Hi Patrick,

Thank you for your reply. But I still don't know how to write the code.

How I would approach this:

1. Using a command prompt get the unzip command right

2. Unzip the file and get the data step right

3. Paste the unzip command into the filename statement (you will have to get the quoting right here).

4. In the infile statement use the fileref so that it points to the pipe where the filename pipe writes to.

Everything here with examples:

From the 7zip help file: the command line should be something like :

7z x yourFile.zip -so

where 7z is the name of the command line version of 7zip, x means extract and -so means write to standard output stream.

@Linlin

I possibly don't understand what the "asc" in your question stands for. But the main approach remains: You use a non-SAS command to bring the archive into a shape where you can read it with SAS and you write this to a pipe which you then access via SAS.
