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.

it is cleared from the stack.
