The exact meaning of [offset someData] in assembly language -

-

my question offset in assembly language

i have written code below :(emu8086)

data segment data1  dw 6 data2 dw 5 ends  stack segment dw   128  dup(0) ends  code segment start:  mov ax, data mov ds, ax mov es, ax    mov bx, [offset data1] mov ax, [offset data2]   mov ax, 4c00h ; exit operating system. int 21h     ends  end start ; set entry point , stop assembler.

i excepted when type [offset data1] receive 6 , when type [offset data2] receive 5.

my reason : offset gives address of data , sign[] give content of mentioned place of memory. when use [offset data1] should receive data1 (here 6)

but result thing else. after running code ax 0006h , bx 0000h , can't understand why.

can please me understand meaning of [offset somedata]?

i know basic i'm new in assembly.

thanks in advance attention

i tried assemble code tasm , received bx=0 , ax=2 expected:

cs:0000 b88f4e         mov    ax,4e8f cs:0003 8ed8           mov    ds,ax cs:0005 8ec0           mov    es,ax cs:0007 bb0000         mov    bx,0000 cs:000a b80200         mov    ax,0002 cs:000d b8004c         mov    ax,4c00 cs:0010 cd21           int    21

in assemblers, mov reg,variable load reg offset of variable , mov reg,[variable] variable contens. not case of masm, interprets mov reg,variable loading reg memory-variable contents , had explicitely write mov reg,offset variable load offset part of variable address. syntax mixed , business of used assembler whether parse mov reg,[offset variable] offset or contents or generate warning. omitt word offset if want load contents of datax. may have specify assume ds:data tell assembler have loaded ds register segment address.
