Thank you very much

Ok. Thank you

I can use all four modes of address in the same program?

Thanks. But:

SUB A #1 // Subtract "1" from A
JZ END // Jump to line with label "END" if A is zero
ADD B 128 // ADD B with the content of 128
JMP LOOP // Jump to line with label "LOOP"

...

Yes. Thank you

I think it is wrong

Yes it was. Thank you very much. Later I will solve the problems posted here, if possible of a look there. Thanks

How works the four modes of address in RAMSES ?
Direct, Indirect, Immediate and Indexed
If possible, an example with the four modes

I want to make a function to fill a matrix. The function receives the number of rows and columns and returns the matrix (User fills in the matrix). I have to use pointer?

Make a program in RAMSES to multiply the contents of the position 128 by content of the position 129, putting the result in positions 130 and 131 (big-endian).


My solution

LDR A #1
ADD A 129...

Make a program in RAMSES that determine the highest value among the contents of the memory positions of 130 to 145, putting the result at address 128


LDR A 130
STR A 128
LDR x #16

LOOP:
...

Develop a program in RAMSES which calculates the average values between 130 and 133 addresses, putting the result at 128


It is correct ?

LDR A 130
ADD A 131
ADD A 132
ADD A 133...

Ok. Thank you

NOT -> not reverse the numbers in binary ?

Acc = 0101
Not Acc = 1010

?

Doing nothing not is NOP ?

Yes I wonder what makes the program, especially the part of the jump

example

What makes this program?

BEGIN:
LDA 130
NOT
ADD 130
ADD 128
JN END1

What are the instructions in Neander ?

Have example ?

I am asking for help, can not?

LOAD mem(0) ACC <-- B
ADD mem(1) ACC <-- B+C
DIV mem(2) ACC <-- (B+C)/D


as do the multiplication separately and then add?

The commands I know are:
LOAD
STORE

I am not asking that they resolved to me. I would like an explanation of how to solve this problem.
