If the environment variable II_W4GL_PASS_NVARCHAR_AS_WCHAR is set to TRUE, OpenROAD passes any user 3GL procedure parameters of the data type nvarchar as wide chars to the user 3GL procedure. If it is set to FALSE, nvarchars are coerced to chars before passing them to the user 3GL procedure. The default is FALSE.

For more information about II_W4GL_PASS_NVARCHAR_AS_WCHAR, see the Workbench User Guide.
