Little Man Computer (LMC)

Could Somebody please help me with the Little Man Computer please.
I have to create a program that will:- Pseudo code

Loop;

input a number;
if number = 0, end program;
if number > 0, add to first number (or sum);
show total;

loopup;

This is driving me crazy. Thank you in advance for your help.

 

Here is the instruction set: http://en.wikipedia.org/wiki/Little_man_computer#Instructions

Just transpose your pseudocode instructions into LMC instructions. There are a few very helpful examples under the instruction set from the link above.

 

Hell pwillener.

Thank you for your reply. In theory your solution is correct.

If this program had to be written in VB, C#, C, C++ or Java I would be fine.
I just cant get used to the syntax of LMC. This is the part that is driving me crazy.

 

Thank you again pwillener.
I took time last night to reflect on what you posted.
the instruction set is really not that difficult if you think about it.
this is the instruction set that made more sense to me

http://voyager.egglescliffe.org.uk/mwc/mukoku/mod/resource/view.php?inpopup=true&id=674

and the program I created is this:

START: INP
IF: BRZ :END
STA :SUM1
ADD :SUM2
STA :SUM2
OUT
BRA :START
SUM1: 0
SUM2: 0
END: HLT

Thank you again pwillener for your in-sight.

 

Sorry pwillener, I ment Hello not Hell
I got the LMC working.
START: INP
IF: BRZ :END
STA :SUM1
ADD :SUM2
STA :SUM2
OUT
BRA :START
SUM1: 0
SUM2: 0
END: HLT
That was it. All that stress for that.
Again thank you pwillener

 

Great; congratulations! :cool
