SET TEXT SIZE sets the text size.
If you want to set the colour you need to use the INK command.
do
cls
ink rgb(255,255,255),0
text 0,0,"fps :"+str$(screen fps())
ink rgb(0,255,0),0
text 0,15,"green"
ink rgb(255,0,0),0
text 0,30,"red"
loop
The ink command is too slow to use in a loop unless you have the second parameter as 0
ink rgb(255,255,255),0 : `runs fast
ink rgb(255,255,255),rgb(0,0,0) : `runs a lot slower
You can also store the colours in an integer which might be quicker than the rgb command,
green as integer
green = rgb(0,255,0)
ink green,0
