Question about the return value

[cymqqqq]

I have some questions about the aluvm:

1. if I want to return a value in the aluvm script(whatever it is), what kind of instruction should I take? (Now there is a ret instr, but it returns nothing)
2. if I want to call another transition or extension, can I use call instr to call the lib id(hash) of a specific transition?

In any registry-based assembler values are returned via registers. And there is no such thing as "calling other state transition or extensions": the question just doesn't make sense, like "how to call CNN from AluVM"
