k Stacks
The unit employs memory blocks, called stacks, for storage of low priority values and
commands. There is a 10-level numeric value stack, a 26-level command stack, and a 10-
level program subroutine stack. An error occurs if you perform a calculation so complex that
it exceeds the capacity of available numeric value stack or command stack space, or if
execution of a program subroutine exceeds the capacity of the subroutine stack.

Numeric Value Stack Command Stack
# Calculations are performed according to the
priority sequence. Once a calculation is
executed, it is cleared from the stack.
# Storing a complex number takes up two numeric
value stack levels.
# Storing a two-byte function takes up two
command stack levels.
