A friend just asked me what this means. Now, yes, I do know that 100-10=90. The whole thing looks like something that would pop up if your computer is hacked or otherwise vandalized. So, TM, anyone ever encounter this particular expression before?

Start with the sequence 100 , remove the sequence 10, leaves 0 .

INU is the middle three letters of MINUS

so the answer is NOT INU means “I didnt remove MS from MINUS” ??? WHich seems one of an infinite number of things not done… (we don’t normally provide a list of things we didn’t do.)

It looks like Fortran code - specifically, the “.not.”

Fortran is an older programming language used primarily for scientific calculations these days.

I don’t know Fortran that well but I don’t think that snippet has any profound meaning. It just looks like something cut and pasted out of a larger program.

I’ve done Fortran programming and that isn’t particularly valid Fortran syntax. Yes, .NOT. is a keyword but it isn’t a binary operator so “0 .NOT. INU” doesn’t mean anything and “100 - 10” isn’t valid on the left of an equals sign.

(To be fair, I’ve seen some Fortran compilers that take some pretty weird things but I can’t imagine that producing any kind of reasonable results)

ETA: Do you have a context for the question? Where did they come across this?

Yes, as it stands it isn’t sensible Fortran, well almost. There are some appalling things that you can do with Fortran IV syntax, and that might actually just about pass muster.

Col. 1 : blank, or a “c” or “\*” denotes a comment  
Col. 1-5 : label  
Col. 6 : any char here marks a continuation of the previous line

100-10=0.NOT.INU

100-10 Almost a label  
= Continuation of previous line  
0.NOT.INU Fragment of a line - needs the previous line to make sense of it.

We could almost be there, especially with a older compiler that was not too fussy. But still probably not. Whilst we have eliminated the 100-10 as an illegal l-value, we still have a unary .not. that won’t quite work with any r-value before it. It would be a pretty odd compiler that would suck 100-10, but some might consider it as label 100 and discard the rubbish.

Fortran used to accept such lovely things as:  
DO9I=1,9 as perfectly valid. It means something very different to DO9I=1

My guess is it’s a “debug” statement that the programmer made that likely would mean little to anybody not seeing where and why it was generated in the source code. Any maybe not even then.

Interesting responses thus far. More info on the situation:

Korean, you say?

Unicode for Korean seems to build individual Hangul symbols from groups of three [jamo](http://en.wikipedia.org/wiki/Jamo) (syllable glyphs).

I find it an interesting coincidence that there are three-letter groups of letters amongst the periods there. I wonder if they were supposed to be the initial, medial, and final jamo of two different Hangul words?

ETA: I just realized we’re commenting on a the contents of a text message from one Korean to another Korean, with no indication of where [Monty](http://boards.straightdope.com/sdmb/member.php) or any of us fit into the picture. I just became somewhat uncomfortable with the idea of critiquing someone else’s private communications.

But a line label wouldn’t be valid on a continuation line. Oh, I can conceive of a compiler maybe accepting it, and if it did it might be possible to contort such a construction into something useful, but it’s nothing any sane programmer would ever dream of.

**Sane programmer**?

I know what both words mean, but their juxtaposition is illogical.

Knowledgeable informants.

The initial recipient has, as in the past, requested views of native (or native ability) English speakers and the sender is aware of that. Also, no effective personal identifying information is present. Well, unless the line in question turns out to be some kind of Super-Duper QR Code and, well, then how cool would that be!

I guess this is what passes for mystery in Korea these days.

One [Infamous error message](http://www.multicians.org/hodie-natus-est.html) was in Latin, stating “HODIE NATUS EST RADICI FRATER”, i.e. “Today is born the brother of the root”, apparently referring to the root of a logical tree, i.e. the node that is believed to be the root actually is a descendent of another node that has another child. It was left in the code because nobody assumed that such a tree malfunction would actually occur.

“100-10=0.NOT.INU”

10=0 not in you

100 flaccid penis

.NOT.INU penis is not in you
