Hi,
I copy/pasted the above line into a blank program, added Blue_On_Time VAR WORD to the top and it compiled just fine for a 16F628.
Code:
Blue_On_Time VAR WORD

write 10,Blue_on_Time.highbyte

END
Try removing the complete line, then re-enter it or copy/paste it from your own post. Perhaps there's some strange hidden character or something lurking. Like I said, compiles just fine here.

/Henrik.
