FMSLogo Code

Uppercase VOWELP in the example.

Improve implementation of VOWELP in the example
Using MEMBERP instead of a chain of IF instructions is more in the spirit of Logo.

Remove the sentence about multiple parallel slots (copy&paste error)
FILTER does not support multiple parallel inputs.

Remove unneeded parens from FIND example.
This makes the example look cleaner.

Improve the example for FIND.
- Give the conditiontemplate procedure a clear name/purpose
(instead of clumsily implemented :arg = 1)
- Show an example of when the template matches multiple
elements of the data input.

Remove the sentence about multiple parallel slots (copy&paste error).
FIND does not support multiple parallel slots.

Move the example explanation from a comment in the code listing to a surrounding <para>.
This was done for conformance to the style guide.

Make HELP documentation begin with a sentence fragment.
This was done for conformance to the style guide.

Replace "360.0" with "360".
The ".0" is needed in C to prevent truncation, but not in Logo.
Including it is misleading at worst, and looks weird at best.

Fix a copy&paste error
The second example was deleting the wrong window. This had the same behavior, since deleting an unknown window name deletes all windows, but it wasn't clear why.
