assembly code on linux

Hello!
I just start learning assembly. I learn it at school on windows. I also want run it on my linux box, with nasm, and it had problems. this is the code:

Code:

cseg        segment
assume      cs:segment
start:      mov ax, 4000
            mov ds, ax
            mov si, 1000
            mov ch, 88
            mov ds:[si], ch
cseg        ends
end         start

nasm output was:

Code:

irst.asm:1: error: parser: instruction expected
irst.asm:2: error: parser: instruction expected
irst.asm:8: error: symbol `cseg' redefined
irst.asm:8: error: parser: instruction expected
irst.asm:9: error: parser: instruction expected

I don't know what the problem is, but on widows it worked. Someone told me the I need to change some orders to unix. Does it true? What to change?
And another question: I try install the ald assembly debugger. It a good debugger? There is something better?

One thingi rememberfromthe nasm manual is "NASM does not ASSUME"

Anyway your syntaxis wrong... you needto use nasm syntax
