That's an
incremental compiler to P-code. Also, in the earlier versions
(RSTS-11, for the no-MMU PDP-11s) it included multitasking
(timesharing) support in the P-code machinery. The later versions
(RSTS/E) didn't need that because there was a real kernel with MMU
hardware.
P-code to a virtual machine, or just tokenized to save parsing time?
I thought it was just tokenized because there were "de-compilers"
that restored "compiled" code to real source.
