Looks like a recursive-descent parser that emits instructions in memory as it parses. Then it executes them immediately (sectorc.s): ;; done compiling, execute the binary execute: push es ; push the codegen segment push word [bx] ; push the offset to "_start()" push 0x4000 ; load new segment for variable data pop ds retf ; jump into it via "retf"
