TEXT x, y, string$ [,alignment$] [, font] [, scale] [, c] [, bc]
'c' is the drawing colour and 'bc' is the background colour. They are optional and default to the current foreground and background colours.

If your display supports transparent text set bc to -1.
If not using other optional parameters you still need a coma to show where they belong.
Eg TEXT x, y, string$ , , , , , -1

Transparent Text
The VGA or HDMI video output or LCD displays using the SSD1963, ST7796S, ILI9341, ST7789_320, or ILI9488 with MISO connected are capable of transparent text.
In this case the TEXT command will allow the use of -1 for the background colour. This means that the text is drawn over the background with the background image showing through the gaps in the letters.

The catch is when you change the text it will be on top of the old text so the total number of characters needs to be the same by adding leading or trailing spaces to equal the longest line.
eg
This works for VGA mode 1 but for colour modes you will need to save an image of the area where the text is going to be (before running the program perhaps) with:-
SAVE IMAGE file$, x, y, w, h
and load that image before changing the text.
