Hello Tom,
JMP 5 terminates a program
Just a minor nitpick: that will be `jmp 0' (with cs = PSP). `call 5' performs a syscall with the syscall number in the cl register. (Also, I recall --- if I remember correctly --- the actual CP/M-86 actually exposes a different `int 0xe0' interface for syscalls; and MS-DOS's `jmp 0' and `call 5' interfaces were actually based on the 8080 version of CP/M.)
