What is this?

SAS can read directly from any text file. Moreover SAS can read directly from any data source that has text file properties, such as FTP, HTTP, or XML, also from named pipes and DDE hotlinks.

When intending to read from a plain text file, you simply specify path and filename along with a description of the record structure. The text file shall look like this:

Royal Inn#King's Suite#4#540
The European#Standard#1#120
St.Peter's#Business#2#333
