Not to be picky or anything, but all conditionals are Boolean because they rely on Boolean logic (as opposed to, for example, fuzzy logic or ternary logic). The use of TI-Basic's representation of true and false as 1 and 0 in optimizations like A+(A=0) should have a different name, because it describes a different concept.
Weregoose suggested "inline conditionals" at United-TI. I don't object to that, but I'm curious to find out what terminology, if any, is used by C programmers who use the same trick (because it works in C as well).
In fact, the word "Boolean" itself seems to be overused in discussing TI-Basic. I've rarely seen a situation in which "Boolean logic" could not be replaced by "binary logic" or just "logic". The TI-83+ manual refers to the logical operators and, or, xor, and not( as "Boolean operators", and that's the only place the word is used.
