Personally I'd rather not rely on it.  It's unpredictable where the 
text will be printed, and you don't have as much control.

`textout' is more powerful, e.g. it can use various fonts and colours
and can put the text at a specific location on the screen. In any
case, Allegro provides a function (`textprintf') that does a
`sprintf' followed by a `textout' for you.
