Truth-Machine

A truth-machine implementation constitutes the following code tmema's competence.

Please heed that, as a corollary of the sb language's carency in an output facility's provision, the number one (1), if committed by the user, is perpetually inserted on the stack, in lieu of its textual display, thus, ultimately, limining the semblance of an infinite loop.
