13.5 - Understanding How Data Sets are Read | STAT 481https://onlinecourses.science.psu.edu/stat481/node/11When SAS compiles the SET statement, SAS adds a position to the program data vector for each variable in the input data set. SAS gets the variable names and attributes, such as type and length, from the input data set.

Effective Data Exploration Using First. & Last In SAS PDV ...https://www.analyticsvidhya.com/blog/2015/04/first-last-sasSAS uses the value of the FIRST.variable and LAST.variable to identify the first and last observations in a group. SAS places FIRST. variable and LAST. variable in the Program Data Vector (PDV). Then, they become available for DATA step processing but SAS does not add them to the output data set as they are temporary in nature.

Understanding Data Step Processing using PDV

The Program Data Vector is a logical area of memory that is created during the data step processing. SAS builds a SAS dataset by reading one observation at a time into the PDV and, unless given code to do otherwise, writes the observation to a target dataset. The program data vector contains two types of variables.

Do you understand the Program Data Vector? - SAS Usershttps://blogs.sas.com/.../25/do-you-understand-the-program-data-vectorWhile the PDV is most commonly associated with reading raw data into a SAS data set, a PDV is also created whenever the DATA step contains a MERGE, SET, MODIFY or UPDATE statements. More importantly, default processing may behave differently.
