Read Text File with DSL (from Fraktal SAS Programming)
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
|Code executed||Function performed|
||Generate a file reference with OS path and file name incl. extension.|
||Initiate data step processing with a DATA statement.|
||Use fileref from above as source with the number sign '#' as field delimiter.|
||Allocate field space by supplying length in bytes and data type.|
||Specify data structure on text file.|
||End the data step run-group (use "cancel" for syntax check only).|
||Clear file reference thus un-locking the file referenced.|
When issuing the phrase "vt hotels" in the command window of your SAS session, the following table might pop-up in a "Viewtable Window":
|Royal Inn||King's Suite||4||540|
