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

Documented Code

Code executed	Function performed
filename source "&PATH.\&FILENAME.";	Generate a file reference with OS path and file name incl. extension
data hotels;	Initiate data step processing with a DATA statement
infile source dlm = '#';	Use fileref from above as source with the number sign '#' as field delimiter
length hotel $16 category $16 no_of_beds rate_in_GBP 8;	Allocate field space by supplying length in bytes and data type
input hotel $ category $ no_of_beds rate_in_GBP;	Specify data structure on text file
run <cancel>;	End the data step run-group (use "cancel" for syntax check only)

Results

When issuing the phrase "vt hotels" in the command window of your SAS session, the following table might pop-up in a "Viewtable Window":

hotel	category	no_of_beds	rate_in_GBP
Royal Inn	King's Suite	4	540
The European	Standard	1	120
St.Peter's	Business	2	333
