limited by the screen size. This results in that, when the display is fully
extended, the top-most row in will only be partially visible (thus indicating
that the user can use scrolling to reveal it). On the plus side, you can now
see up to 31 rows on an iPad Pro!

0 n CON, i.e. withg a zero-size width, is now an error; it will no
longer create an empty array.
0 →LIST no longer fails; it creates
an empty list.
SAME will return 1 for items of the same value,
e.g. 2 == as well as value equivalency, you would need to run a program
like: « OVER TYPE OVER TYPE SAME ROT ROT SAME AND ». Tip: store
this in a valuable named 'EQUAL'.
Dropped support for iOS 8 and 9.
This version needs iOS 11 or later.
Added an option reduce motion in the startup animation. Prior to iOS 8, the
default is "Off". On iOS 8 or later, this setting will be pre-set to mirror
the value of the "Reduce Motion" setting of the General > Accessibility pane
of the main Settings application. However, once the value is changed in the
settings panel within the app, that value will be retained and used from then
on, irrespective of what may be set in the Settings application.
Fixed: The grey Copy & Paste Shortcut bar will no longer appear,
whether or not Bluetooth is enabled. Previously, it would appear when Bluetooth
was on, and the bar would then stay until the app was restarted.
