Yes, some of the Casio pocket models only allowed 'blind' programming, like this 61F, so we don't see what commands we inserted and there is no way to edit a program.
But these specific models didn't had real programmability in mind, as the machine was designed to natively offer most of the required features to most of the target users.

As I see it, these tiny small pocket machines were very popular among students and even professionals exactly due to is portability and great number of specialized features. We cold just put it in any pocket and we didn't notice it was there thanks to its small size and weight.
