== This page does not explain what in interpreter IS ==
This page does not explain what in interpreter IS but rather discusses all the technical minutia which is uninteresting to an average reader like me. I just want to know what an interpreted language is. Could someone please someone make this page simpler?

I think we should remove that code. It's too long and technical for the average reader, and it doesn't really convey anything. Plus it's in a nasty language. [[User:Cgs|CGS]] 11:40, 24 Aug 2003 (UTC).

:The main problem with Lisp is that you would also need to supply a lisp-machine of some sort to run the Lisp interpreter on. I have implemented a version of the SECD machine in BASIC which could be used but the combination of QBASIC, SECD machine, SECD Lisp interpreter and Lisp Lisp interpreter is quite complex to load and wouldn't really be any easier to understand than the current interpreter since the "elegant" interpretive top layer relies on a rather "uncouth" compiled substrate. Looking on the bright side of course, it would be more general since it would be able to interpret user defined functions and lambda expressions. -- [[User:Derek Ross|Derek Ross]] | [[User talk:Derek Ross | Talk]] 06:01, 2004 Dec 15 (UTC)
In the first paragraph, it states that "the first interpreted high-level language was probably Lisp." It seems like the "probably" can be nailed down. I don't know where this could be researched, however. Having "probably" seems a little mealy-mouthed.

== Why is an interpreter defined as a computer program? ==
Line 55 ⟶ 57:
:I think that that is a perfectly reasonable view and worth adding to the article. Please do so. However the article does capture the more commonly used meaning of ''interpreter'' which is normally applied to computer programs which translate in a particular repetitive way. I think that it would be going too far to remove the discussion of that meaning. Both are important. -- [[User:Derek Ross|Derek Ross]] | [[User talk:Derek Ross | Talk]] 02:04, 2004 Jun 25 (UTC)
: Also, microcode is out of sight in most architectures except x86, and even then it's only used for particular operations.--[[User:Blaisorblade|Blaisorblade]] ([[User talk:Blaisorblade|talk]]) 03:16, 6 August 2010 (UTC)
: Yeah, so many articles assume something has to be a program when in fact it doesn't. I just edited the intro heavily and one thing I did was to say an interpreter is software ... which means it could be a program, but need not be.[[User:Stevebroshar|Stevebroshar]] ([[User talk:Stevebroshar|talk]]) 12:16, 9 August 2025 (UTC)

: I believe this section, that was added by a single user (albeit somewhat cleaned up by another well-meaning user) should be deleted. It is unsourced and somewhat arbitrary, and amounts to essentially [[WP:OR|original research]] and [[WP:SYNTHESIS|synthesis]].

An anonymous user (68.197.139.156) added a paragraph (compare [https://en.wikipedia.org/w/index.php?title=Interpreter_(computing)&diff=522863651&oldid=519912762 the delta]) on Nov. 13, 2012. I considered fixing the grammar, but decided to delete it. '''Reasons:'''
<ol><li> The intent and role of this paragraph are not clear (to me).</li>
<li> There are some minor factual errors. At the very least, some sentences are misleading.</li>
<li> The paragraph duplicates other parts of the article:

== information missing ==
Isn't some kind of interpreter also used when dealing with natural language input to computer programs? This aspect does not seem to be discussed in the article. <small><span class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Skysong263|Skysong263]] ([[User talk:Skysong263|talk]] • [[Special:Contributions/Skysong263|contribs]]) 18:01, 22 March 2010 (UTC)</span></small><!-- Template:Unsigned --> <!--Autosigned by SineBot-->

:I see now That there are Forths that do optimised compiles rather than just producing threaded code, why anyone would want to do that for a write only like that I don't know. It is not though a good example of compiling for the article I believe. [[User:Dmcq|Dmcq]] ([[User talk:Dmcq|talk]]) 10:05, 11 May 2010 (UTC)
== Citation and Non Sequitir ==
At present this article does a rather inadequate job of inline citation (see other users above me). It also has other issues with citation in a more practical sense. Even when a source is included at times it is included without contextual information and so the information presented is less then useful. A very important example of this occurs when the article gets to the LISP section and mentions "McCarthy". The first time the name is reference it is done without any context who McCarthy is or why one should care what he has to say. I could add "Donges" says to various articles and the rightful response would be "Who is Donges? Why do I care what he has to say. Now it may be that McCarthy is a well known expert in some field. That material still needs to be there to suddenly start referencing him as this is an Encylopedia article not a 1specialty manual. By way of a parallel example, I would not include a statement in an article about the C program attributed to [[Dennis Ritchie|Ritchie]] without at least at first indication of whom he was. To read at present an individual without computer background reading the article may think that McCarthy refers to former U.S. [[Joseph McCarthy|Senator Joseph McCarthy]] and honestly I do not really care what suprises Senator McCarthy about LISP. <span style="font-size: smaller;" class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/98.237.41.200|98.237.41.200]] ([[User talk:98.237.41.200|talk]]) 07:31, 27 November 2011 (UTC)</span><!-- Template:Unsigned IP --> <!--Autosigned by SineBot-->

== Not satisfied with first sentence ==
The first sentence makes it sound as if the CPU is executing instructions that haven't been compiled into machine language, and that's impossible. The CPU is only executing the interpreter. The interpreter process, running in the CPU, reads and maps the code to compiled routines within the interpreter, thus calling/executing machine code. The script or code here acts like data, and just triggers the execution of compiled code.

:First, you should include text rather than saying something like "the first sentence" bc the first sentence changes over time. That said, I think whatever you were talking about is no longer the case. [[User:Stevebroshar|Stevebroshar]] ([[User talk:Stevebroshar|talk]]) 12:12, 9 August 2025 (UTC)

== Hardware interpreter ==
This article is all about software interpreter, but... you can build an interpreter in hardware. In fact, a CPU is a hardware interpreter! But, we don't think of a CPU as interpreter. We generally think of 'interpreter' as meaning software. None-the-less, I'd say the current article name [[Interpreter (computing)]] does not match the content. Either the article should mention hardware interpreter or should be renamed to [[Interpreter (software)]].
