Each pulse applied to the clock input increments or decrements the number in the counter. Operation V increments the semaphore "S", and operation P decrements it. The "P" G-Counter counts increments; and the "N" G-Counter counts decrements. Advanced age is associated with decrements in episodic memory. Each reboot decrements the counter by 1. Each process that terminates decrements it by 1. It seems likely that multiple factors are responsible for the observed decrements. The original version presented the numbers every 2.4 seconds with 0.4 decrements for subsequent trials. Each application launch decrements it by 2. Destroying a reference decrements the total weight by the weight of that reference. Decrements storage register zero, and skips the next instruction if the result is zero.
