Indeed, this is a very bad thing to do -- certainly it will fail big time
under MiNT, and probably under RTX and other systems (including, perhaps,
future versions of TOS).

There is an AES call that can get the program name if the program was
started from the desktop. If you were started from a shell that supports
the mwc/Atari extended argument passing conventions, the program name
is put in the environment after the variable ARGV=. Some C compilers
will automatically put this into argv[0] (gcc and mwc will).
