just like from binary file, there is no difference, but you have to code all routines like word-recognising, finding end-of-line etc. yourself. one of biggest disadvantages of ASM - you don't have standard libraries

If you are writing program for Windows, you can use function from msvcrt.dll library. For example:


Code:
READ_ACCEDD db 'r',0

proc read_text_file, .pszFileName
local .tfile:dword, .pStrBuf:dword

    push ebx edi esi

    invoke LocalAlloc, LMEM_FIXED or LMEM_ZEROINIT,1024   ; Allocate space for string to read
    mov [.pStrBuf],eax
    
    cinvoke fopen, [.pszFileName],READ_ACCESS   ; Open text file for reading
    mov [.tfile],eax

.startloop:   ; Get string from text file one by one and store it in [.pStrBuf]
    cinvoke fgets, [.pStrBuf],1024,[.tfile]
    test eax,eax
    jnz .startloop

    cinvoke flose, [.tfile]
    invoke LocalFree, [.pStrBuf]

    pop esi edi ebx
    ret
endp

i'd recommend you to use pure windows api (CreateFile, ReadFile, CloseHandle)

MSVCRT.DLL is a part of the Microsoft Win32 API. It is not one of the core libraries, but it is a member of the API. I believe also that CreateFile and ReadFile may actually make calls to some of the file handling procedures in the C runtime libraries.

Actually it's the other way round. Also, you will not find the MSVCRT functions in the Microsoft's Win32 API reference.

Microsoft's Win32 API reference as it's name suggests is only about APIs shared for ALL windows programs. MSVCRT is C/C++ library only. It doesn't mean one cannot use it in asm/delphi/vb/... but it is not their purpose.
But you can find all needed info in C/C++ reference (just as: www.msdn.com)
