*lle | lri | ule | uri txt* _text_ 
{indent}Will display text in lower left | lower right | upper left | upper right corner of the screen.{indent} 
*cur | ref | min txt* _text_

*fam 1 | 2 | ... | 9*
{indent}Use font family 1 / 2 / 3 /.../9{indent}
*coor* _xcoor ycoor | xcoor ycoor zcoor_ 
{indent}Position in world coordinates _xcoor ycoor_ for fixed x y placement (not using the *fol* argument) or _xcoor ycoor zcoor_ for using the *fol* argument.{indent} 
*screen* _xpix ypix_ 
{indent}Position from lower left corner in pixel positions _xpix ypix_.{indent} 
*col whi | red | gre | ...* 
{indent}Select color for display.{indent} 
*col* _r g b_

*use* 
{indent}Use the current color.{indent} 
*fol* 
{indent}Use the follower for the text to follow the camera. In that case the command must know the x y and z coordinates to place the text. This is achieved with arguments *cur* or *coor* or *poi*.{indent} 
*poi* _pointnumber_ 
{indent}Display the text in the poisition of point _pointnumber_ of active data. Points are counted from 1.{indent} 
*txt* _text_ 
{indent}To display a text, put it in braces or double quotes if the text contains spaces.{indent}
