Here one needs to understand the contextual inference of the Symbol, the easiest way to understand the scenario is when used in arithmetic calculations the plus/minus signs are considered as infix operators, Similarly, when used in the definition the symbols are categorized in Prefix operators. The questions arise in terms of a definition of plus and minus signs in SAS programming. Subcategories of Infix operators are as follows

Infix Operators: They are referred to those operators acting upon both the sides of the operators, these operators have generally involved in arithmetic as well as the logical operations in SAS programming.

It is also to be mentioned that the word NOT and its equivalent symbols are also considered as prefix operators. Let us now try to understand examples of Prefix Operators

Prefix Operators: It is a general expression used in defining the operators which are applied on the operands (are constants or variables that can be numeric or character) which follow the expression, the activity associated with the operators is applied immediately on the variable, expression, constants.The segregation between the two is based on the modus operandi of the operators. There are two major categories of operators in the SAS programming language which include Prefix Operators and Infix operators. The SAS operators are symbols used in programming for arithmetic, logical or comparison operations. PROC STEP: It is used to process the data.DATA STEP: It is used in dataset creation and variable assignment.The SAS program is built on the two building blocks:. SAS was initially developed in 1966 to cater to the life sciences industry with primary use being in predictive analysis using variance and regression legacy data, SAS further developed its ability with the incorporation of JMP to combine with the Graphical User interface option provided in early MAC, with the continuous development philosophy and advancement in computational ability of scientific systems and the increasing load of omnipresent data SAS introduced data mining features in 2005.įurther development in the suite provided various features like excel import, experimental designing,Īs of now, SAS is extensively used in providing Customer intelligence solutions, SAS also finds huge applications in Banking industries with the ability to identify fraudulent transactions, SAS products are also used in government, retail, telecommunications and aerospace and for marketing optimization or high-performance computing.
