Thanks for the response.
It makes a lot of sense to post a comment on the Manual page where a question arises, and where others may offer answers. It saves time and hassle searching -- which may or may not yield results to questions.
This is how comments on manuals are structured in various open source projects, such as MySQL and many others ...
In fact in the MySQL manual pages you will find commenter offering sample code how to use SQL functions in variously efficient ways.
