Wow! Thanks for that, I've got a lot to take in from the generosity of posts.  I will download the circle worksheet for further study.

Thank you.

I appreciate the extra info there, I'm pretty much a beginner with Maple, so any extra insights are welcome.

Thanks

Dave

@Christopher2222

Thanks for your post.  It now works fine, thank you.

## @Matt C Anderson  Thanks for your ...

Thanks for your response, it is very helpful and amusing.  As you could guess I'm fairly new to Maple and entirely new to MaplePrimes, but I'm grateful that it exists.  Mapleprimes will be a very useful resource for me in the future.

Much appreciated, Dave

## Spaces in Names...

I found the answer to my Spaces question.  Spaces are allowed provided the name is enclosed in single quotes.  Otherwise no.

Does Maple allow spaces in Names?  It didn't seem to when I was trying names earlier.

Thanks, Dave

## See Below...

Thanks for your response, I found the green up arrow.  The last line of my worksheet is the error message that I can't get rid  of to continue working.

SECTION 1.9 NAMES, SYMBOLS and STRINGS

Any expression may be assigned a name.

Names should satisfy the following criteria:

 • Starts with a letter, followed by zero or more letters, digits and underscore characters. Uppercase and Lowercase are distinct.
 • Names can be formed by enclosing any sequence of characters in a pair of left single quotes, i.e. 'This is a name'
 • Any name formed with quotes is identical to names formed without quotes, i.e. x and 'x' are both the same name x.
 • Names can be formed with the || cat operator
 • Names should NOT begin with an underscore or a tilde and should not contain a slash.

Ex. 1.24:

 >
 > This_is_a_valid_name :=2;
 (1)
 > I_like_this_number! :=42;
 (2)

Join names

 > i := 5;
 (3)
 > p || i;
 (4)
 > p|| 2*i;
 (5)

If RHS is a sequence or range with integers or character strings

then Maple returns a sequence.

 > a ||(a, b, 4, 67);
 (6)
 > "foo" || (1..4);
 (7)
 > Trees_aren"t_pink!;
