Well, to make a long story short, the program reads your .txt (or any source), parses the expressions (BISON/FLEX/YACC), and writes the appropriate machine code:

For example (INTEL FORMAT):
--test.s--
SEGMENT .data
MSG DB 'Hello World', '$'

SEGMENT .text
MOV AH, 09h
MOV DX, MSG+256
INT 21h

MOV AX, 4C00h
INT 21h
----------

nasm test.s -o test.com

EXAMPLE:
MOV AX, 4C00h ---> B8 00 4C
