Only numeric characters are changed. Letters, commas etc. are
skipped. The numeric characters are interpreted as a associated deci-
mal number. This decimal number is increased or decreased by 1.
In order to avoid flickering, the old display is not cleared until after the
new display content is outputted.
The background colour used with the variables may not be transparent,
and a character set with uniform character width should be used in order
to assure correct display. Otherwise, the variable must be cleared prior
to the change, and then displayed once again!
Variable content is stored to RAM only. After the device has been
switched off and back on again, the variables are returned to their pre-
configured values.
