SAS is driven by SAS programmers who use several sequences of operations on the SAS datasets to make proper reports for data analysis.Over the years SAS has added numerous solutions to its product portfolio. It has solution for Data Governance, Data Quality, Big Data Analytics, Text Mining, ...
combine datasets using inexact character variables, and implements this algorithm using SAS® software. When this algorithm is used together with PROC SQL it allows combining the datasets based on several inexact variables,...
More often than not, there are a series of SAS programs that you run in a sequence, with different types of output directed to different locations, along with all the intermediate and final SAS datasets that are generated. 2 Enterprise Guide provides a mechanism to organize your work by ...

my ToothGrwoth_VC dataset in a similar way, but the output is an empty dataset when I run the same code, but replace the "ToothGrowth_OJ" with "ToothGrowth_VC". Is there a way to use the subset code to take these two separate datasets and combine them into one, or an easier way?

SAS has a lot of datasets that might have more than n number of values on the two different datasets values by the conceptual domains. These two reference datasets are closely isomorphic to the exceptional values of the outside of the intersection to propose a threshold percentage and sizes to...
