this is the data format on startup:
(vax) ap and fp are unpredictable as far as I know; don't use them.
sp -> word containing argc
- word pointing to first arg string
+ word pointing to first arg string
[word pointing to next arg string]... 0 or more times
0
Optionally:
/* On the 16000, at least in the one 4.2 system I know about,
the initial data format is
sp -> word containing argc
- word containing argp
- word pointing to first arg string, and so on as above
+ word containing argp
+ word pointing to first arg string, and so on as above
