When combining Work.Ds_One and Work.Ds_Two with PROC APPEND, what is true regarding the process?

When using PROC APPEND to combine two data sets, the FORCE option is not inherently required unless there are issues with data set compatibility, such as differing variable types. However, when the variable names and types are aligned, which would typically be the case if both data sets are structured similarly, PROC APPEND can be utilized without the FORCE option.

In this context, the resulting data set will include the variables from both data sets, preserving the column names and structures. If the original data sets Work.Ds_One and Work.Ds_Two have variables named X and Y, along with corresponding values (e.g., 1, 2, 3 for one set and A, B, C for another), the outcome would logically maintain the naming conventions and appearances of these variables rather than transforming them or introducing a workflow that would necessitate the FORCE option.

Considering the layout and sequencing, the correct choice reflects that the FORCE option is not necessary, and the combined data set retains the original variable names and formats, producing a coherent dataset reflective of these inputs. Thus, should the two datasets share this structure, the outcome is a resultant data set containing the variables correctly named and organized in the expected manner.
