I am aware of upper-case() and lower-case(), but does anyone know if there is a function for initial capitalization or do I need to build my own? Forgive my ignorance, I searched the spec and did not see one, but wanted to post this question before defining my own.

Thanks.

There isn't one (in truth there are very few programming languages that provide such a facility).

A combination of concat() and substring() can be used to achieve the same effect.

What do you mean by initial capitalization? The first letter of the string? The first letter of every word? The first letter of every noun? The first letter of everything except adverbs and prepositions (which seems to be the rule that Wrox copy-editors are using, even "Is" gets capitalized, which looks very strange to British eyes).
