No. In the COBOL example PARA-1 though PARA-4 are consecutive
paragraphs, not functions that are terminated by a return (explicit or
implicit).  If you want to think of it as a function, the paragraphs
are all part of a single function, but both the entry and return
points of the function are variable, specified by the caller!

No one claimed that it wasn't possible to achieve the equivalent
effect of such a program using normal constructs of other languages;
it would just have to be structured differently.
