Me too.
it's easy to write without GOTOs in FORTRAN...
IF (0) 902,902,902
is the same as
GOTO 902
Again, I'm left speechless. I wonder if I would have gotten credit on
all my assignments where they took off points for goto spaghetti...
I should mention that if you want to really obfuscate things, you
could do something like
IF (0) 901,902,903
because you know that only 902 will be a target. And, almost all
compilers could figure out that the argument is fixed, so it would
emit a JMP $902 or whatever... You could make the other targets
something really obscure, and hopefully many pages away, and rather
than make the argument a constant, some complex expression that
always evaluates to the same value (like those "think of a number" puzzles).
Good for detecting copyright infringments, eh?
