* These instructions require an address on second instruction to be complete.
A single location in program/data memory can hold only a two-digit number. Most
instructions occupy one location in program memory, with a single key code. The
two-digit addresses needed to make instructions for data memory, program library
access or special control operations complete are not stored with their instruction
but occupy a second location in memory. Unconditional transfer addresses which have
an address of three-digits are stored in three locations.

The calculator handles instructions that require more than one memory location
automatically, advancing program pointer ahead according to number of locations

when working mean standard deviation calculations. They are available for normal
use for any other operations.
