Registers. app for iPhone and iPad

Registers is a simulator for the Register.
The registers uses a limited set of basic instructions to operate. These instructions are enough to write programs that represent computable functions. Usually the state of the execution starts with the arguments in the initial registers, and the output is served the first register. Registers can be modified during execution. The set of instructions is:

- Z(n): set to 0 the register n
- S(n): add 1 to the register n
- T(m,n): move the content of the register m to the register n
- J(m,n,q): if the content of register m is equal to the content of register n go to instruction q
