 I didn't ment my contribution as a programming tip but wanted to complete the
statement that PDL() has nothing to do with the buttons.
 It *does* work as described by me on an Apple ][+ and was documented by Apple
in the Apple ][ Reference Manual which tries to explain the hardware as it is.
 Nowadays  Apple  has  a stronger feeling for ensuring upward compatiblity and
includes in its manuals the concepts of what the various features are supposed
to fullfill.
 I  should have stated that in my original message to avoid this confusion and
agree  that  there  is  realy too much software unnecessarily losing with each
hard/firmware upgrade.
