R_WORD is a REALTIME operator that displays a single word of text on the screen. The position of the text display is specified by POINT, an array of 2 integer values for X and Y. TEXTSTR can either be a simple character string variable or a string list variable. WORDNUM specifies which word of the text string to display, with the first word being WORDNUM 0. Words are defined as a group of text separated by spaces (ASCII 32) or newlines (ASCII 10). Multiple separators in succession are treated as one. Unlike R_TEXT, R_WORD does not increment string list variables in TEXTSTR.

The FLG variable is a bit flag that can be used as follows:

    1 - center the displayed text at POINT
    2 - before displaying text first clear previous text at that POINT
    4 - adjust POINT to point to the end of the displayed text
   16 - adjust POINT to point to 1 space after the end of the displayed text

If MAXCHAR is specified and non-zero it will be used as the maximum number of text characters that will be displayed.
