INPUT SB parameter ERROR

[Javier_Gonzalez2 (Javier González)]

Hello.
I am testing NaturalOne.
As I remember on mainframe this program runs successfully.
Where the problem is ?

[system]

According to the documentation

Selection boxes in an INPUT statement are available on mainframe computers only. On Windows, selection boxes may be defined in the map editor only. On UNIX and OpenVMS, selection boxes cannot be defined and are ignored, if they are imported from a Windows or mainframe environment.
