You can see that all the data contained on the magnetic card has been
loaded into the proper storage registers. The data also remains record-
ed on the magnetic card, and can be loaded into the calculator over
and over, until you record other data or a program on that card. Data
(like programs) may be loaded into the calculator from a card in any
order—no matter which side you first pass through the card reader,
the calculator identifies it and places the contents in the proper storage
registers of the calculator.
