Never used them myself, but could envision where they could be helpful in a
complex DATA Step code generation scenario (macro) wherein names or
templates are passed into a macro.
In general, I would say that the functions were part of the effort by SAS to
surface the all attributes of DATA Step PDV elements and compilation
structures to the dynamic (runtime) environment.
If the speculation is so, one would wonder where are these functions:
- VOBJECT(name, '<component-object-class>'), such as
