Assignments of standard HP-41C functions to key locations consume one
register (seven bytes) for each odd-numbered assignment made. For example,
the first assignment made consumes one register, the second assignment
consumes no additional space, the third assignment consumes another full
register, the fourth consumes no additional space, and so on. Assignments of
programs that you have written and stored into program memory do not require
any additional space; the assignment is stored with that program’s label.
