Are HP 39gII programs HP Prime compatible

[Jim Horn]

I'm enjoying my HP 39gII. Its programming language appears to be a subset of the Prime's. Is that true? Specifically, would programs I write be of any use to anyone besides other '39gII users?

I know that the Prime programs I've tried have not worked on the '39 but haven't delved into why yet. Obviously, without a CAS, color display, touch screen and so on there have to be differences. But before I delve into finding them myself I wondered if such information is available already.

*Many thanks* indeed to the intrepid developers at HP and the contributors in this forum!
