I'm previewing the book now. 

From the intro chapter .. "This book is intended for students, teachers and researchers who will ultimately wish to use Maple for advanced applications.  Here, 'advanced' means something more complex than evaluating a single integral, but not necessarily designing and running a simulation of the latest jet engine."

The "not necessarily" really gets your mind buzzing.  I'll have to check it out in the new year.

I wonder if Maplesoft can use the info and make a better interrupt button? 

For some additional information to help with a better interrupt.  If the output of a calculation is extremely large, or if the output is just simply large to begin with, the interrupt will not work.  Maple appears to have stopped while the information is being passed to the display.  I don't know if the interrupt button, or improved interrupt button, can help in this case but using the output suppression colon at the end works most times.  However in case one forgets the colon, it would indeed be helpful for the interrupt button to work.

Interesting, that would be MapleV version 5 shown.  For historical interest here is my copy of MapleV version 3 and what was included in the box.

Interestingly when I look back, the Maple versions which stand out for me are of course MapleVr3 then Maple 9.5, Maple 10, Maple 12 and Maple 18.

Actually regarding Maplesoft manuals I don't even know if they even offer hard copy manuals to buy.

I want to add a new field or additional attribute to a particular record.  So in my example the green honda doesn't have a model associated with it, so I'd want to add (append) 'model'=accord to that field.  I guess the trouble with that is that if it hasn't been initially entered or it doesn't have a unique name in the field it would be a little more difficult to add. 

Regarding the full list of the Record - disregard - I was sleepy.  However getting a nice layout list would be better, with some coding it could be layed out in a table.

@Carl Love How would I call the full list of the Record and how would I add an attribute to a particular field?

@Carl Love thanks that's what I was looking for.

I suppose if it were a question it would be, what is the minimum number of folds possible for values from 1 to 10?

@Carl Love It was a post, I don't know who turned into a question?  There is no question, you are correct.

@tomleslie thanks for that.  I didn't realize a fraction would have cleared that up so easily. 

Using the :- option Maplets:-Elements seems to throw an error every other time you run it in Maple 2016.1

**edit added** I should have added the sample code it alternates errors with restart; without restart; line it seems to work fine.

restart;
with(Maplets:-Elements): 
maplet := Maplet([BoxCell(ListBox([seq(StringTools:-Random(15, 'alpha'), i = 1 .. 20)]), 'vscroll = always')]); Maplets[Display](maplet)

Ok vscroll is the required option.  Shouldn't that be automatic if the ListBox list is beyond a certain size?

with(Maplets):
with(Elements):
maplet := Maplet([["Pick a color:  ", ListBox['LB1'](sort(["blue", "red", "wheat", "yellow", "brown", "gold", "plum", "orange", "pink", "khaki", "magenta", "maroon", "white", "green", "aquamarine", "black", "gray", "navy", "coral", "cyan", "sienna", "tan", "turquoise", "violet", seq(i, i = "a" .. "z")], lexorder))], 'vscroll = always', [Button("OK", Shutdown(['LB1'])), Button("Cancel", Shutdown())]]):
result := Maplets[Display](maplet)

If I break up the with statement it works without error

with(Maplets):
with(Elements):
maplet := Maplet([["Pick a color:  ", ListBox['LB1'](sort(["blue", "red", "wheat", "yellow", "brown", "gold", "plum", "orange", "pink", "khaki", "magenta", "maroon", "white", "green", "aquamarine", "black", "gray", "navy", "coral", "cyan", "sienna", "tan", "turquoise", "violet"], lexorder))], [Button("OK", Shutdown(['LB1'])), Button("Cancel", Shutdown())]]):

However if I execute it together it brings an error

with(Maplets[Elements]):
maplet := Maplet([["Pick a color:  ", ListBox['LB1'](sort(["blue", "red", "wheat", "yellow", "brown", "gold", "plum", "orange", "pink", "khaki", "magenta", "maroon", "white", "green", "aquamarine", "black", "gray", "navy", "coral", "cyan", "sienna", "tan", "turquoise", "violet"], lexorder))], [Button("OK", Shutdown(['LB1'])), Button("Cancel", Shutdown())]]):
Error, `Elements` does not evaluate to a module

@Joe Riel Maple 2016.1

In Maple 18 it sometimes works and sometimes doesn't depending on if a colon exists at the end of maple:= but with Maple 2016.1 removing the colon doesn't help.

@ Markiyan Hirnyk What result does Mathematica give?

If you expected more from the LimitTutor then it is perhpas the command just needs improvement.
