It is easier to recall A than to remember where it is in the
stack.

!
Replaces old A with new result.
Recalls constant for comparison.

Loops With Counters (DSE, ISG)
When you want to execute a loop a specific number of times, use the z
k
( increment ; skip if greater than ). or
{ m
( decrement ; skip if less
than or equal to ) conditional function keys. Each time a loop function is
executed in a program, it automatically decrements or increments a counter
value stored in a variable. It compares the current counter value to a final
counter value, then continues or exits the loop depending on the result.
For a count–down loop, use { m variable
For a count–up loop, use
z k
variable
These functions accomplish the same thing as a FOR–NEXT loop in BASIC:
variable = initial–value
!
final–value
