Can anyone answer this question regarding the difference between "bsr" and "jsr":

"jsr" is an absolute jump to a subroutine.
"bsr" is a relative jump (8-bit, 16-bit, or 32-bit signed offset) to a
subroutine,
i.e. typically for calling a nearby function.
There's also "jbsr", which is an assembler macro that picks the most
appropriate: bsr does not need relocation, but bsr.l is 68020+ only.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
