I cannot find an explanation why a boolean evaluation with higher Digits is not the same

RealRange seems to be evaluated differently.
Any explanation for that?

I was about to review a piece of code which is the "main procedure" of a worksheet (as one would say in other languages).

What I mean by that are the top level code statements of a Maple worksheet which are not part of procedures. For the code example I can easily put everything into a procedure and invoke the Maple debugger. For larger worksheets this becomes complicated.

For this reason I was wondering whether the debugger can also be started for a complete document.

For a month I did do not get email notfications.

I checked spam folders, settings and email filters.

Is it only me?

Why does dsolve not call odetest by default before a solution is returned?

I mean, why do I have test each result separately. dsolve could have an odetest option (default=true).

In case of discrepancies dsolve could inform the user and suggest to call dsolve with odetest=false and run odetest separately to analyse the problem.

Set up this way, dsolve would never return potentially incorrect solutions that do not pass odetest.

I cannot find anything in the documentation that could explain the below.

The variable palette only lists the name entered in 1D.

What could explain the difference between 1D and 2D when "?" is used in a name.
