I note that in the documentation
RIDE 4 is supported on Raspberry Pi models 2 and 3 only; models Zero and 1 are not supported (the underlying libraries which RIDE is build on are not available for the Pi Zero and 1).
I assume that the documentation is only referring to running Dyalog APL on the Pi while also running (via localhost - 127.0.0.1) the "Remote IDE" locally on the Pi.
To me, the documentation seems to suggest that Ride 4.0 and 4.1 (running on any platform) cannot be used to access Dyalog running on a Pi Zero etc, when this is clearly not correct.
<Sticking tongue firmly in my cheek>
Is there a case for referring to running "RIDE" when in Local mode as "LIDE" (Local IDE).
