In this module, you'll use advanced functions to compare data between multiple rows in a SAS table, find and count substrings within a column, and clean and standardize data. You'll also explore CALL routines, Perl regular expressions, and how to use advanced functions to modify and analyze storm, weather, and population data.

In this module, you'll learn how to use arrays to simplify your code. You'll use arrays to process repetitive code, rotate data, and perform table lookups.

In this module, you'll learn how to declare a hash object, instantiate or create an instance of the object, and initialize its lookup keys and data. You'll use the hash object to store and retrieve data, create an output table from the data in the hash object, and create a hash iterator object to process the data in a particular order.

In this module, you'll learn how to use PROC FORMAT's PICTURE statement to create a custom template to display large numbers, dates, and times. You'll also use PROC FCMP, the function compiler procedure, to create custom functions and CALL routines.
