Complete SAS Programming Guide - Learn SAS and Become a Data Ninja - Reading Data Instream in Data Step (Typing Data Rig

The video tutorial explains how to read data directly into the coding area, known as reading data in stream. It covers two types of data: free formatted and fixed formatted. Free formatted data uses delimiters like spaces, while fixed formatted data requires column definitions due to the absence of delimiters. The tutorial provides examples and explains how to define columns for fixed formatted data, ensuring proper data alignment.

What is one advantage of reading data in stream compared to importing it?

• It is easier when dealing with small data sets.

• It is more secure.

• It allows for larger data sets.

• It requires less coding knowledge.

What is a characteristic of free formatted data?

• It uses column definitions.

• It requires special software to read.

• It has delimiters like spaces.

• It is always numeric.

In the context of free formatted data, what does the 'cards' statement indicate?

• A special type of data format.

• The end of the data input.

• The beginning of a new data set.

• That data will follow this statement.

What is a key difference between free formatted and fixed formatted data?

• Free formatted data is more secure.

• Fixed formatted data requires column definitions.

• Fixed formatted data uses delimiters.

• Free formatted data is always larger.

Why are column definitions necessary in fixed formatted data?

• To ensure data is imported correctly.

• To convert data into a different format.

• To define the space each variable occupies.

• To add delimiters to the data.

How do you determine the space needed for a variable in fixed formatted data?

• By using a special software tool.

• By counting the number of letters and spaces.

• By guessing based on the data type.

• By using delimiters.

What should you do if a brand name in fixed formatted data is shorter than the maximum length?

• Leave it as is.

• Add extra letters to fill the space.

• Ignore the discrepancy.

• Add spaces to match the maximum length.
