the result in the d1splay and storage registers at step

is the
same as in step 03 of the original program; one step has been
saved. However, by using this alternative form it is necessary
to press the CONT (continue) key twice to run the program;
the first time to start the program and the secend time after
the data is entered. With the original program CONT has to be
pressed only once, after data entry (see Page 69 for use of
CONT key).
