With variables decisions can be made, conditional show
starts or counter can be realized.
Variables can be manipulated inside a show or through
external events. Possible actions are setting a value of a variable
or executing mathematical operations like add, subtract, multiply
or divide. A variable can also be loaded with the content of
another variable.
Basically there exist two types of variables, RAM-variables
and EEProm-variables. The RAM-variables are only valid during
the runtime of the device and lose their content after power off.
After power up, they are set to the value 0.
The EEProm-variable keeps their value also after power off.
Therefore, they can be used for example as a show-counter.
ATTENTION!
Although both types of variables may be handled
in the same way, RAM-variables should be used in
general, if there is no need of saving the content
after power off.
The variables are addressed by a number, where the numbers
1 to 70 refers to the 70 RAM-variables and the numbers 71 to
100 the 30 EEProm-variables.
