I was wondering how I could detect the min and max of a list of 12 numbers using LC-3 Assembly code. Any help would be appreciated. Thanks in advance.

Does anyone know how I could do this? How would I do an array or even compare two numbers to see which one is larger/smaller? I would appreciate any help.

68:

[code]var min = MAX_VAL; // largest possible value for an element

var max = MIN_VAL; // smallest " " " " "

for p = 0 to 11

if min < list[p] then min = list[p];

if max > list[p] then max = list[p];

next p[/code]

8: :

:

: [code]var min = MAX_VAL; // largest possible value for an element

: var max = MIN_VAL; // smallest " " " " "

:

: for p = 0 to 11

: if min < list[p] then min = list[p];

: if max > list[p] then max = list[p];

: next p[/code]

Thanks for the reply but the assembler language I'm using only has AND, ADD, NOT. It doesn't have "if" and "<>". If it did, this would be so much easier. Lol. I actually figured out the program since I submitted the request. Thanks though.

1I am still tyring to work it out. I have the code and it should work, but the simulator is doing something weird... we can't figure it out.

Hi. I got problem with that too, can you put the code for me to detect min and max numbers ? Thanks
