/* REXX ---------------------------------------------------------------
* 09.02.2014 Walter Pachl with a little, well considerable, help from
* a friend (Mark Miesfeld)
* 1) downstripped an example contained in the ooRexx distribution
* 2) constructed the squares for seconds, minutes, and hours
* 3) constructed second-, minute- and hour hand
* 5) removed lots of unnecessary code (courtesy mark Miesfeld again)
* 6) painted the background white
* 7) display date as well as time as text
* 21.02.2014 Attempts to add a minimize icon keep failing
