SAS/STAT 12.3 and 12.1 User's Guide

Reading Sample Data from a URL

You can use a DATA step to read sample data directly from the URL of a SAS/STAT example. Specify the URL in an INFILE statement; the DATA step reads from the HTML source of that URL. To determine the URL of a SAS/STAT example, select the example from the Example Programs (Sample Library). The following DATA steps read the data from Example 4 for PROC ADAPTIVREG, whose URL is http://support.sas.com/documentation/onlinedoc/stat/ex_code/121/adptex4.html.

Writing Data to the SAS Log

The following DATA step writes to the SAS log the HTML lines that start with the line following the <pre> tag and end with the line prior to the </pre> tag.

Submitting the Sample to SAS

The following DATA step writes to a file (junk.junk) the HTML lines that start with the line following the <pre> tag and end with the line prior to the </pre> tag. The %INC statement submits the file to SAS.

Submitting the Sample, Title, and Comment Block to SAS

The following DATA step writes to a file (junk.junk) the initial comment block, the title, and the HTML lines that start with the line following the <pre> tag and end with a line that contains a single semicolon in the first column. The %INC statement submits the file to SAS.

Not all samples end their DATA steps with a single semicolon in the first column. Depending on the sample you are reading, you might need to change the statement IF _INFILE_ EQ ';' THEN PRE = 0;. For example, if the semicolon that ends the instream data set in the sample is in the fourth column instead of the first column, replace ';' with '   ;'. That is, insert three spaces before the semicolon but inside the single quotation marks.
