In many programming languages, there is a function named eval() that can be used to evaluate an expression and return the result at run time. For example, in Python, the eval() function parses the expression passed to it and runs a Python expression or code within the program. Even Python

In my new book, End-to-End Data Science with SAS: A Hands-On Programming Guide, I use the 1.5 IQR rule to adjust multiple variables. This program utilizes a macro that loops through a list of variables to make the necessary adjustments and creates an output data set. One of the most
SAS' Leonid Batkhan describes programming technique for creating multi-purpose SAS® Macro functions.
The stored compiled macro facility enables you to compile and save your macro definition in a permanent catalog in a library that you specify. The macro is compiled only once. When you call the macro in the current and subsequent SAS® sessions, SAS executes the compiled code from the macro
SAS® offers several ways that you can find the top n% and bottom n% of data values based on a numeric variable. The RANK procedure with the GROUPS= option is one method. Another method is The UNIVARIATE procedure with the PCTLPTS= option. Because there are several ways to perform this
Have you ever written a macro and wondered if there was an easy way to pass values to the macro? You can by using macro parameters. Macro parameters enable you to pass values into the macro at macro invocation, and set default values for macro variables within the macro definition.
When developing SAS applications, you can feed database tables into your application by using the libname access engine either by directly referring a database table, or via SAS or database views that themselves refer to one or more of the database tables. More on Automation with SAS: Let SAS write
Have you ever needed to run code based on the client application that you are using? Or have you needed to know the version of SAS® software that you are running and the operating system that you are running it on? This blog post describes a few automatic macro variables
