One last question on this.. Kind of stuck in that:
What is the routine, if my equation is n = 1 - i^2 ?
I'm a little new handling minus numbers in hex.

With Virtual 8085 I get 2 errors.
line 2: only 8-bit second operand.
I changed that with:MVI A,00H
line 7: Invalid register specified.

Ok, i think that do the job!

MVI B,03H
MVI A,00H...

I found something with some help...
This:

MVI A,00
MVI C,0AH
LXI D,0100H
LOOP: STAX D
INX D
INR A
DCR C
JNZ LOOP
...

MVI A,0
MOV A,B

loop CMP 05,A
BEQ end_for

ADD 01,B
ADD 01,A
JMP loop
end_for HLT

I think this must be better..
Error in line 4: Invalid command.

Yes, sorry..
I get:
unfinished code in line 3.

I look your comments and tried to adjust my program. I think i correct these :

The code is now :

//multiply a[2][3] * b[3][4] = c[2][4]
//with fork
//each child completes one c[2][4]'s row
...

I'm trying to correct the code. i have this now:

//multiply a[2][3] * b[3][4] = c[2][4]

#include<stdlib.h>...

Looking for it and will reply back!
Thanks :b:
