When you perform a test, (like, for example, 2<3) the TI-92 will return, 
literally, true.  It is an expression that does not have a number 
assigned to it.  On the TI-8X series, the same test will just return a 
1.  If a function function has a boolean, it will not return a number, 
but an error. (To be exact, it's Error #160: Argument must be an 
expression)

It's a very subtle change, but an annoying one for programmers 
translating for the TI-92.
