Dear everyone

How to run assembly language under DOS?
Is it directly entered after the command prompt or do you need any program? Please give more advice ah!!!!!!!!!!!!!!!!!

Assembly language needs to be assembled and compiled into an executable file before it can run. The following is a batch file I wrote. The required platform is Microsoft MASM version 6.11, installed in the C:\MASM directory.
@ECHO OFF
GOTO TOP

Corrected specially according to the correction pointed out by friend willsort.

Great expert! Admirable!
Thank you very much!!!!!!!!!!!!

Well written, thank you!!!

Thanks for the praise. Everyone, did you notice that there is a flaw in this batch file? Hehe. There's no need to blame me for this problem because this batch file is only used by myself. When I uploaded it to the forum, I forgot to change the relevant issues. I just noticed it today.

Re Kinglion:

A rather routine batch script, but as you mentioned, since it's for personal use only, there are some localization setting issues, and there are quite a few places that need to be modified. Such a program is fine as an example, but not suitable for application.

Additionally, there is a question for your discussion: "Does assembly language need to be compiled before it can run"? Regardless of the distinction between assembly language and assembly code, just in terms of the term "compile", it seems to be a term that emerged after high-level languages, is it appropriate to apply this term to low-level languages? Whether it is more appropriate to change it to "assemble". Of course, MASM itself has a process similar to compiling high-level languages, but this is because MASM is not a pure assembly language, but a macro assembly language, and the macro instructions and pseudo-instructions contained in the code it supports require the existence of this process. Another commonly used assembly instruction environment DEBUG indirectly verifies this problem. The assembly sub-command -A in it supports the 8086/80286 assembly instruction set. The process of handling assembly instructions is "assembling" similar to the "interpretation" process of high-level languages, not "compiling".

To willsort:
What you said is right, some of my words indeed have many places worthy of discussion, thank you for your correction. Hope to have more exchanges with you.

Your level is really high.
I don't understand this aspect and haven't studied these before. Now I just discovered this website, so I will follow you all to learn in the future, okay?
I'm still a layman in computers, please give me some support.
Thank you everyone.
