Definitions
The definition of memory1 is done in every loop of the program; we only have
to do it once. It also slows down the program cycle time.
In order to do it only once we create a main procedure without the definitions that
runs in endless loop. The definitions are declared in the program (under the Start
program block). After the declarations, the program runs the main procedure.
