What it does
TextColorAlpha takes textID (an integer), and answers an integer. That is the first of 2 forms. textID 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")DO Print(TextColorAlpha(text)) Sync()LOOPForm 2, you choose the id yourself
text = CreateText("hello")TextColorAlpha(text, 255)DO Sync()LOOPCreateText is there to give the call something to act on; TextColorAlpha 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.
