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
!
