Casio fx-3800P "Programming"

I think there are a lot of other lacking features I would address before worrying too much about those.

Anyway, there are plenty of alternatives for those on Casio's symbolic programming models (fx-4000P/EC-4020, fx-7000G, etc.) which also don't allow them in conditional tests.

And: Just string two conditions together.

X>0=>X<Y=>Goto 4

Or: Either write the conditions+predicate multiple times, or if that's too wasteful (lots of conditions, multiple statements in the predicate, etc.), logically invert the conditions you're testing and jump over the conditionally executed code with a Goto.

If you're talking about bitwise And/Or for Base-N mode, then those might be doable with what passes for programming on the 3800P. Not sure.
