Part of this stems from the fact that the actual memory footprint of a series of discrete objects in TEMP is not the same as the memory layout of a list containing those same objects in TEMP. So there's not a direct way to simply "remove the list prologue and SEMI" and put pointers to all the elements on the stack.

Yes I think what you're describing is what I was hoping for. Sounds like it's not as straight forward as I had hoped.

Yes was thinking there must be a way just didn't know how feasible. Guess if it was easy someone would have done it already

My main working program is on the HP48 SX which I have the program in a protected port 2. The main program is at 80k and supporting libraries take up the rest of the port. I use port 1 as merged memory which gives me a reasonable amount of ram. So saving to a port will usually not help much from a memory aspect in this case.

On the version I'm making for the hp50 I may save data to the port as there is more memory do so. On a separate topic I'll probably create a separate post for I'm having program speed issues when running my program as a library on the hp48G, hp49G or hp50G. I think it's related to the forced GC when I run the MEM command from a library opposed to a program stored as a variable.

Thanks for the feedback and hope your able to find a workaround for your list project the list functions look very useful.
