Complete SAS Programming Guide - Learn SAS and Become a Data Ninja - SCAN Function

This video tutorial explains the scan function, demonstrating its use with the catX function to extract first and last names from a concatenated string. The instructor uses a consistent example to illustrate how to apply the scan function effectively, highlighting common mistakes and providing clear steps to avoid them. The tutorial emphasizes the importance of understanding the interaction between scan and catX functions for efficient data manipulation.

What is the primary purpose of using the same example in multiple lessons?

• To introduce new examples every time

• To confuse the students

• To make the lessons longer

• To build on new concepts more easily

What does the scan function do when applied to a variable?

• It scans and extracts specific parts of the variable

• It merges two variables

• It deletes the variable

• It changes the variable type

How can you extract the first name using the scan function?

• By using the argument 'name' and '1'

• By using the argument 'result' and '2'

• By using the argument 'name' and '2'

• By using the argument 'result' and '1'

What argument should be used to extract the last name with the scan function?

• The argument 'name' and '1'

• The argument 'result' and '1'

• The argument 'result' and '2'

• The argument 'name' and '2'

What is a common mistake when using the scan function?

• Trying to scan variables that are not concatenated

• Using the wrong delimiter

• Using the scan function without arguments

• Forgetting to use parentheses
