Whether you are a SAS code creator, a blogger, a technical writer, an editor-in-chief, an executive, a secretary, a developer or programmer in any programming language or simply someone who uses computer or hand-held device for writing, you need to read this blog post – your life is about to
In my prior posts (Data-driven SAS macro loops, Modifying variable attributes in all datasets of a SAS library, Automating the loading of multiple database tables into SAS tables), I presented various data-driven applications using SAS macro loops. However, macro loops are not the only tools available in SAS for developing
The ancient political maxim “divide and conquer” (Lat. “dīvide et īmpera”) has been used for millennia in politics, sociology, and psychology, mainly to manipulate people. In the last two centuries, however, this principle has also been adopted by computer science. It is widely used in computer programming, primarily in computer
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
Even if you are a traditional SAS programmer and have nothing to do with cybersecurity, you still probably have to deal with this issue in your day-to-day work. The world has changed, and what you do as a SAS programmer is not just between you and your computer anymore. However,

Small matters matter. Imagine saving (or spending wisely) just 1 second of your time every hour. One measly second! During your lifespan you would save or spend wisely (1 sec-an-hour * 24 hours-a-day * 365 days-a-year * 100 years) / (3600 seconds-an-hour * 24 hours-a-day) = 10 days, a whole
Imagine making $50K a day out of thin air. Did you know that NASDAQ routinely processes around 10,000,000 trades a day? What if instead of rounding cents for each transaction, market makers truncated fractions of cents in the amount they owe you? Under the assumption that each transaction, on average,
Using the DATASETS procedure, we can easily modify SAS variable attributes such as name, format, informat and label: proc datasets library=libref; modify table_name; format var_name date9.; informat var_name mmddyy10.; label var_name = 'New label'; rename var_name = var_new_name; quit; We cannot, however, modify fixed variable attributes such as variable type
