Assignment 3 Question 2

Hi,

I don't know if anybody if this far yet, but I am struggling allot with this question. It seems that I totally miss interpreted the sample programs that they provide in the study guide, because when I attempt this question nothing works.

I really don't hope that this is the type of questions we will be seeing in the exam !!!

Cheers,

If you give me an idea of which part you can't do, I think I can help you. I have a semi working version of the whole program, if i type my input as B7 I get MOV 23 and not MOV AL,[23]. So in effect my program gives the right answers but does not add in all the extra formatting.
To add the formatting is difficult for the following reason

PUSH 23 should be formatted as PUSH [23]
POP 23 should be formatted as POP 23
ADD 23 should be formatted as ADD AL,[23]
SUB 23 should be formatted as SUB AL,[23]
JMP 23 should be formatted as JMP 23
MOV 23 should be formatted as MOV AL,[23]
JE 23 should be formatted as JE 23
RET (No matter what number) should be formatted as just RET

So depending on the instruction the output needs to be formatted differently.

Thanks for the offer, but it seems that I finally got some of it to work. Sounds like I am basically at the same point in the assignment as you are. I now just need to go and work on the final formatting, but I must say .... it is a mission trying to keep track of all the registers as you are coding !!!!!

Assembler just makes my appreciate 4th and 5th generation languages SOOOOOOOO MUCH more !!!!!

Hi Guys

I am totally lost. Please point in a direction where I can find my feet.

I figured out how to read the characters from the keyboard and how to print to the screen.

I have no idea how to go about solving this.

How do you declare a array existing of 8 5-byte strings?

Hi here's how I have done it. Try make lots of use of procedures to prevent getting lost in a jumble of code.

;------------- Array of Opcodes-------------------------------------
Opcode: db 'PUSH$','POP $','ADD $','SUB $','JMP $','MOV $','JE $','RET $'
;-------------------------------------------------------------------

thats gr8. Thanks
