select all varchar variables in SAS Viya

[gyambqt]

Hello experts,

Is there a way to select all Varchar variables in CAS table using datastep in Viya?

initially I thought to use array: test[*]  _varchar_ but it didn't work.

As far as I can tell from the documentation, even in SAS Viya, the only variable lists defined seem to be _ALL_, _NUMERIC_, and _CHARACTER_.
Have you tried _CHARACTER_ yet?
