How to extract an element that has been defined as a range from a vector?

[Cornel]

Hello,

How to extract for example the 13th element from below?

Hi,

The creation of x makes it a range variable not a vector of scalars.  An undocumented trick to turn the range into a scalar vector is to use inline equals in the definition.

[Cornel]

I have a question here: can this undocumented trick fail? And if yes, then when can it fail?

[terryhendicott]

Never had the trick fail.  Here is the "correct" way

It will fail if PTC at some point, in a later version of Prime, makes it impossible or unusable.

So far that hasn't happened, but there's so much that hasn't happened with, or by, PTC over the past more than 10 years.... the chance that things will happen can only grow over time.

Success!
