Activation Records on Stack Based Machines

Hello,


        I'm actually new to code generation techniques dealing with
function invocation/declaration. I am working on a small imperative
language that uses a stack based virtual machine. I've searched/read
about activation records, but all I found was register-based machines
way of pushing activation records on the stack. Where do I place the
return value of a function, save program counter, allocate space for
local variables...etc. Can someone give me pointers on how that can be
done on stack-based machines? Or even documents that explain how
Python, Java, or any other language that uses a stack-based VM
implements activation records?


regards,
