UCV.write
UCV.wri
Print graphical text on to the cover
Intention
This command will print text in the actual foreground color. Use the "UCV.foreground" command to set the foreground color. "UCV.write" will use the font that you can set using the "UCV.set font" command.
General usage is simple:
UCV.nbi
UCV.grd|&H00FF00
' Set red foreground color
UCV.fgr|&HFF0000
' Print in red onto the green background
UCV.write|Hello world!
' We change color to yellow
UCV.fgr|&HFFFF00
UCV.wri|Hello world!|200,200
' This will remove the Cover

Will look like this:
UCV.write will not automatically do a "word wrap". Therefore avoid words that do not fit into a line, as these may be cut off at the end otherwise. Use the "UCV.print" for such cases to have word wrap.
UCV.write will allow you to exactly specify the top,left corner of the text to print. Like this:
UCV.write|Hello world!|100,100
UCV.write will allow you further, to specify an alignment as a third parameter:
UCV.write|Hello world!|100,100|2
See below for details.
