Paper 121	Kirk Paul Lafler and Stephen Sloan	Application of Fuzzy Matching Techniques Using SAS® Software - A Panel Discussion	Fuzzy matching techniques are available with most, if not all, the leading software languages including R, Python, Java, and others (RosettaCode, 2018). SAS Institute offers four techniques for its users: the Soundex (phonetic matching) algorithm, and the SPEDIS, COMPLEV, and COMPGED functions to help make fuzzy matching easier and more effective (Sloan and Lafler, 2018 and 2021).
			The Soundex (phonetic matching) algorithm involves matching files on words that sound alike. Although the Soundex algorithm does a fairly good job with English-sounding names, it frequently falls short when dealing with the multitude of data sources found in today's world economy where English- and non-English sounding names are commonplace. The SPEDIS, or Spelling Distance, function and its two arguments evaluate possible matching scenarios by translating a keyword into a query containing the smallest distance value. Because the SPEDIS function evaluates numerous scenarios, it can experience varying performance issues in comparison to other matching techniques.
			The COMPLEV, or Levenshtein Edit Distance, function is another fuzzy matching SAS technique. COMPLEV counts the minimum number of single-character insert, delete, or replace operations needed to determine how close two strings are. Unlike the SPEDIS function and COMPGED function (discussed later), the COMPLEV function assigns a score for each operation and returns a value indicating the number of operations. The COMPGED function is another fuzzy matching technique which is facilitated by a SAS function. It works by computing and using a Generalized Edit Distance (GED) score when comparing two text strings. The Generalized Edit Distance score is a generalization of the Levenshtein edit distance, which is a measure of dissimilarity between two strings (Teres, 2011).

Paper 107	Richann Watson and Louise Hadden	Functions (and More!) on Call!	CALL subroutines are similar to SAS functions; however, you cannot use CALL subroutines in expressions or assignment statements, nor can they be nested.
			SAS has a myriad of CALL subroutines and functions, however, there may be situations where what you need is just not available as a pre-defined SAS subroutine or function. PROC FCMP allows you to create your own subroutine or function.
Paper 112	Kirk Paul Lafler	Demystifying PROC SQL Join Algorithms	A join of two or more tables provides a means of gathering and manipulating data in a single SELECT statement. Joins are specified on a minimum of two tables at a time, where a column from each table is used for the purpose of connecting the two tables using a WHERE or ON clause.
			When it comes to performing PROC SQL joins, users supply the names of the tables for joining along with the join conditions, and the PROC SQL optimizer determines which of the available join algorithms to use for performing the join operation. There are four algorithms used in the process of performing a join: - Nested Loop – A nested loop join algorithm may be selected by the SQL optimizer when processing small tables of data where one table is considerably smaller than the other table, the join condition does not contain an equality condition, first row matching is optimized, or using a sort-merge or hash join has been eliminated. - Sort-Merge – A sort-merge join algorithm may be selected by the SQL optimizer when the tables are small to medium size and an index or hash join algorithm have been eliminated from consideration. - Index – An index join algorithm may be selected by the SQL optimizer when indexes created on each of the columns participating in the join relationship will improve performance. - Hash – A hash join algorithm may be selected by the SQL optimizer when sufficient memory is available to the system, and the BUFFERSIZE option is large enough to store the smaller of the tables into memory.
			There are operational and syntax differences between inner (natural) and outer joins. Like an inner join, an outer join relates rows in both tables. But this is where the similarities end because the result table also includes rows with no related rows from one or both of the tables. This special handling of "matched” and "unmatched” rows of data is what differentiates an outer join from an inner join.
Paper 116	Kirk Paul Lafler and Josh Horstman	The Battle of the Titans (Part II): PROC REPORT versus PROC TABULATE	Our focus for this paper and presentation is to explore an assortment of scenarios describing general concepts that users will most likely encounter when using PROC TABULATE and PROC REPORT.
			The primary goals for PROC TABULATE are to form and present hierarchical tables of summary statistics using the data values of classification variables to define hierarchies. PROC TABULATE supports three-dimensional tables, tables with pages, rows, and columns. TABULATE was designed to support arbitrarily complex nestings and concatenations of table elements in each dimension. So TABULATE provides users with a lot of flexibility.
			The syntax for TABULATE is a challenge for a lot of users. Some form of simplification was in order. The approach taken with PROC REPORT is to limit the number of dimensions and to support a simpler COLUMN statement. Even that COLUMN statement had to be complex enough to support nestings of ACROSS variables and other elements. It is also necessary to offer detail reports with more formatting options than PROC PRINT afforded. PROC REPORT supports both GROUP and ORDER variables to generate both summary and detail reports.

Paper 153	Richann Watson	Have a Date with ISO®? Using PROC FCMP to Convert Dates to ISO 8601	While SAS has a number of functions and subroutines to handle a variety of things, they do not have one for converting dates to the ISO 8601 format. With PROC FCMP you can create your own functions and subroutines to do this conversion and save it to a permanent library for others to use.

			SAS OnDemand for Academics (ODA) provides learners and educators with a comprehensive cloud- and web-based user interface called SAS Studio. SAS Studio provides numerous user-friendly features to help users become more productive while using the SAS ODA. To begin, open one of the supported web browsers (e.g., Google Chrome, Mozilla Firefox or Apple Safari) to access SAS ODA by clicking the following hyperlink, https://www.sas.com/en_us/software/on-demand-for-academics.html, and then clicking the "Access Now”. The SAS Studio User Interface provides users with a powerful and easy-to-use interface and a comprehensive integrated development environment (IDE). The SAS Studio interface is divided into several parts that help make user interaction easier, Navigation pane, and Work area more convenient. Let's explore the different parts of SAS Studio to better understand what they're used for. After signing into SAS Studio, Server Files and Folders provide users with the ability to upload local data files. There are four more dropdown menus below Server Files and Folders, two of which will be emphasized, Tasks and Utilities, and Libraries. SAS Studio's point-and-click navigation provides users with a powerful, flexible, and easy to use approach to auto-generating SAS code for all types of SAS processing. The objective of this paper is to demonstrate the many capabilities that SAS OnDemand for Academics (ODA) and SAS Studio offers users including creating new SAS libraries; establishing library references (LIBREFs); uploading SAS data sets, tab-delimited, CSV, and Excel data files in the cloud; importing tab-delimited, CSV, and Excel data files to SAS data sets using tasks and utilities; and producing results using the Navigation pane.
