' This program allows to display the led sliding from right to lef and one 
' from left to right.
' In order to make an easier visualization of the status lines, it is 
' necessary to get a 20 pins flat cable for connecting GPC(r)F2 CN2 
' connector to TIO 16 CN1 connector, or DEB 01 CN15 connector.
