A little (lot) assembly language help?

[NuclearFusi0n]

This program will have two components:

1. An input routine allowing the user to input a specified number of letters (say 10), which will be stored in an array, i.e. in a sequence of contiguous memory locations.
2. A routine that will sort the stored letters into ascending order (i.e. A to Z), re-store them into the same array, and output them to the monitor.


I sux at this, and have NO clue what to do mainly because i've missed a few classes here and there (damn you 8am class) This is for some LC2 simulator...
If anybody feels like helping me out i will give you a great big nonsexual <3 unless you are a cute woman keke.

well, for the first part why dont you use a loop and index addressing mode? something like this: (i use motorola HC11 MIPS, so the syntax could differ)
LDAA #00
LDX #$base_address_for_storage
loop CMPA #9
BEQ done
LDAB input_number
ST@B 0,X ; hey it stands for STore Accumulator B! I'm sorry!
INCX
INCA
BRA loop

basically, it uses A as a counter, X as the storage location of the 10 digits, and B to take input and store it in the array location. Not terribly difficult. Make sure you define 10 continuious bytes somewhere. As I said, this is for Motorolas HC11E9, so your code will probably differ, but you get an idea.

For the second part, well, I dont really feel like figuring out an algorithm. Off the top of my head, convert to ASCII and compare numbers.

good luck

i'm fvcked. screw it, somebody shoot me.

Assembly is different for different chips. I know assembly for the x86 (knew it) but don't remember enough to help. What you are asking is a huge job in assembly and I doubt anyone will take the time to actually type the whole thing out. Good luck

I've left the lab.

I wish to die,
somebody, please, put a bullet in my eye.
