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

Calculates A – B.

Replaces old A with new result. Recalls constant for comparison. Is B < new A?

Yes: loops to repeat subtraction.

No: displays new A.

Checksum and length: 5FE1 013.5

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 {mvariable

For a count–up loop, use zkvariable

These functions accomplish the same thing as a FOR–NEXT loop in BASIC:

 variable = initial–value ! final–value ! increment
