268 Flags
Create and load a program that stores in successive storage
registers values that you key in during a pause. Use the data
entry flag F3 to make a decision whether to store the number or
merely to wait for another input. Use the flowchart on page 269
to help you. By using the data entry flag F3, you cankey in values
for zero and have them stored too.
When you have loaded the program, run it to check its opera-
tion. You should be able to store up to 26 values (including
values of zero) in succeeding storage registers. Manually recall
a few random values from some of the storage registers to ensure
that the program has operated correctly.
