Complete SAS Programming Guide - Learn SAS and Become a Data Ninja - Flexible Programming 1 - Combining multiple raw dat

The video tutorial demonstrates how to create flexible programs for combining raw data files vertically. It introduces a business scenario requiring monthly reports and explains three methods to achieve this: using the file name statement with a wild card, employing the Infile statement with file VAR, and integrating the month function for dynamic file selection. The tutorial provides detailed code explanations and highlights the importance of file naming conventions and delimiters.

What is the primary goal of the program discussed in the video?

• To combine raw data files vertically

• To generate random data

• To create a graphical user interface

• To encrypt data files

What is a requirement for the files in the business scenario?

• They must be stored in the cloud

• They must be in PDF format

• They must have the same file structure and similar names

• They must be encrypted

What does the wildcard character (*) do in the file name statement?

• It renames files

• It compresses files

• It reads any file that starts with a specified prefix

• It deletes files

In the first method, what is the purpose of the DLM option?

• To specify the delimiter used in the text files

• To change the file extension

• To encrypt the data

• To delete empty lines

What function is used in the second method to concatenate file names?

• JOIN

• CATS

• MERGE

• CONCAT

What does the 'file VAR' option do in the second method?

• It changes the file permissions

• It deletes temporary files

• It stores the result of the CATS function

• It specifies the file format

What is the purpose of the month function in the final section?

• To determine the current month and previous months

• To encrypt the data

• To change the file format

• To delete old files

How does the month function help in processing files?

• It changes the file permissions

• It determines which files to process based on the current and previous months

• It compresses the files

• It renames the files

What is stored in the variable 'monum'?

• The current year

• The file path

• The current month number

• The file size

What is the main advantage of using the month function in the code?

• It changes the file format

• It increases the file size

• It encrypts the data

• It reduces the number of changes needed in the code
