$PROGRAM_NAME
$0 Contains the name of the program being executed. On
some operating systems assigning to $0 modifies the
argument area that the ps program sees. This is
more useful as a way of indicating the current
program state than it is for hiding the program
you're running. (Mnemonic: same as sh and ksh.)

Note for BSD users: setting $0 does not completely
remove "perl" from the ps(1) output. For example,
setting $0 to "foobar" will result in "perl: foobar
(perl)". This is an operating system feature.
