You said it is easier to learn "the right way" and system specific
extensions later, what implies that you consider using argv[0] as a
"system specific extension". Nice that you say that that isn't the case

That is not true, MSDOS sets the value of argv[0] to the name of the
program since MSDOS 3.0, introduced in 1984! That is 27 YEARS ago.

Urban legends. Yes, I should (in a beginners program in 2011) take care
that one of the students uses an msdos version that is older than 27
years. Note that my question was

"... EXISTING system..."

and you come up with MSDOS 2.0, from 1983. GREAT!
