I presume it's not attached by default to "make things easier for the novice user", i.e. basically the same reasoning that got us the stupid algebraic mode as default. At this point, running 256. ATTACH at startup should be as automatic for a power-user as doing -62. SF

I agree with 3298's reasoning and in fact, you don't even have to formally "attach" Library 256, just set flag -86 and do a warm start.

In the spirit of rebellion, I am posting my program for the 50g which uses one Library 256 command, even though it does not qualify. 124.5 bytes, it assumes exact mode and flag -86 set.
