12c clr reg not programmable, why?

[rprosperi]

Since CLR REG destroys all data everywhere (storage and financial registers as well as the stack, including LASTX) it really serves no purpose in a program, except perhaps as the initial step to clear everything in a program which will then go on to initialize values and proceed with calculations, but if so, the user could simply execute CLR REG manually just prior to running the program.

Also, I just checked and confirmed the CLR REG operation also resets the user program counter, thus use in a program would be suicide as it would reset to line 00 and halt.
