What it does
TextCharColorAlpha takes iTextIndex (an integer) and iCharIndex (an integer), and answers an integer. That is the first of 2 forms. iTextIndex is the id of a Text object, the one CreateText returned: it is how the call knows what to act on.

Form 1, the command hands back the id
text = CreateText("hello")char = CreateTweenChar(1.0)DO Print(TextCharColorAlpha(text, char)) Sync()LOOPForm 2, you choose the id yourself
text = CreateText("hello")char = CreateTweenChar(1.0)TextCharColorAlpha(text, char, 255)DO Sync()LOOPCreateText and CreateTweenChar are there to give the call something to act on; TextCharColorAlpha is the line that matters. The DO … LOOP is not decoration: a classic BASIC program ends the moment it runs out of lines, and Sync() is what draws the frame.
