arny.b.engelson (arny@cbnewsl.att.com) gives some figures for
"Hello World" programs on VMS:

Again, an operating system issue. C doesn't really fit with VMS.
Linking C is not as straightforward for other languages. I don't
use C myself, but I think a link command like

   $ LINK prog,sys$input/option
   vaxcrtlg/share

or something similar will cut down the C executable to reasonable sizes.

I like to restress the point I made a while ago: if your tiny "hello
world" program makes the disk explode, don't blame the langauge,
blame the operating system which doesn't provide shareable images.
If the OS does, blame the compiler who doesn't use them.
