In-Stream Data Creation and Display

The first code block uses a DATA STEP to define and populate the 'instream_mtcars' dataset. The variables 'cars', 'mpg', 'cyl', 'disp', 'hp', and 'drat' are defined, and their values are read from the data lines provided after the CARDS statement. The 'cars' variable is defined with a character format of 12. The second block uses PROC PRINT to generate a formatted list of the 'instream_mtcars' dataset's content, allowing for immediate verification of the created data.

Data Analysis

Type : INTERNAL_CREATION

The data is created and integrated directly into the SAS script via the CARDS statement. No external data source is used.

1 Code Block

DATA STEP Data

Explanation :
This DATA STEP is responsible for creating the 'instream_mtcars' dataset. It defines variables and their types (numeric or character with INFORMAT) and reads observations directly from the data lines specified between the CARDS statements and the final semicolon. This method is commonly used for small test or example datasets.

PROC PRINT

Explanation :
This PROC PRINT procedure is used to display the content of the 'instream_mtcars' dataset that has just been created. It allows for visual verification that the data has been correctly read and stored in the SAS dataset. The output is typically displayed in the SAS listing file or in the results section of SAS Studio.
