Hi,
I found out so far, that %3e00.... means, that the data is put on
segment 62 (0x3e). Regarding to the Z8000 ASM handbook, segmented
adresses are notated as <<segment>>offset, so in my case
<<62>>%F600 - but of course it does not work and the assembler
yields and error :(

By any way - is here someone on the list understanding Z8000 PLZ/ASM? ;)
The problem is, that "u" must be available in the address space on this
location for the kernel to function correctly:
# define UBASE 0x3E00F600 /* kernel virtual addr of
user struct */
And with the above ASM code, it is placed on 0x0100F600. I also tried
of course $abs 0x3E00F600 but it makes no difference. It is always
placed at 0x0100F600 and I have zero clue why
the original object from the system:
#67 nm /usr/sys/conf/u.o
3e00f600 A _u
01000000 s u_d
0000 s u_p
my object generated from my u.s:
#68 nm u.o
0100f600 A _u
01000000 s u_d
0000 s u_p
Somehow I need to get the address right.... This is why I wanted to
look up how the original SYSIII or V7 was doing it (even if the asm
would be of course completely different).
