That is pretty much what the license counts (and my gut) have shown over the years.  It has always been hard for the compiler group to count actual customers.  We would get revenue amounts for that was after any discount so if all compiler licenses were discounted to $0, then we would appear to get no revenue.

C++ is becoming just as important as Fortran, COBOL, and C.

I know one customer with a BASIC applications that is over 8 million lines. I'm sure there are more, I just have not met them.

I know several customers with Pascal applications that are just as large.

In the VSI world, it is getting even harder.  While we have some count on Itanium, look at the Alpha license model that only has 

$ show lic /producer=vsi

Active licenses on node GLX2:

------- Product ID --------    ---- Rating ----- -- Version --
Product            Producer    Units Avail Activ Version Release    Termination
ALPHA-LP           VSI             0  H     0      0.0  (none)      11-APR-2019
ALPHA-SYSTEM       VSI             0  A     0      0.0  (none)      11-APR-2019

And the ALPHA-LP license enables all the compilers.
