Standard Variables List

Official Content
This documentation is valid for:

In several GeneXus objects, GeneXus offers pre-defined variables which are of common use. They are named standard variables.

Even though they are not shown by default in all types of objects, if you try to define a variable with the name of a standard variable it will automatically appear with the standard variable definition and you will not be able to define its data type or anything else. In other words, it's not possible to define user variables with those names in any type of object.
