Probably a misspeak.   But FORTRAN is more than simply a language--it's 
a way of life.  :)

The gist was that the notion of an overlay tree was first brought to my 
notice with FORTRAN.  It could be that it had been presented in earlier 
documents as such and evaded my notice., It did take the form of a set 
of subroutine calls, and was not an element of standard FORTRAN.

As mentioned, COBOL had a similar scheme that was embedded in the 
language itself.
