It is my observation (with a sliver of supporting facts) that UNL  
(unnatural language) is at the opposite end of this scale, probably  
under 500 words for a large, mature software application.  My guess  
is that a large immature application would likely have more words—and  
redundancy, multiple labels/terms for the single concept "social  
security number"—since the builders have been sloppy from moving too  
fast & lack of solid architectural specifications.    (04)

Did your/Arun's work with the reverse engineering project show that  
the actual words used in an application are surprisingly small?    (05)

My assumption is that normal NL statistical practices will not work  
well when applied to such a small body of terms.  Is this accurate?   
I am by no means a statistician.    (06)

For comparison... your system was 1.5M LoC, right?  By crude  
guesstimate my system's front end (CICS) was 450 programs @2000  
(guessed) lines each... 900,000 LoC.  That was just the front-end...  
not the DBMS (IMS), the back-end (ETC), or whatever reporting there  
was.  Total for this system was 4.5M LoC.  [Note to audience: lines  
of code (LoC) is a really stupid "measure."]    (07)

The term/word count was 387.    (08)
