I did use TV as well, from the discription of the /WORDS keyword, I was under the impression
that the converion to byte was not done for TVSCL when /WORDS is set. You're right, TV is
more appropriate, I first used TVSCL because I used it in a program I have that opens up a
window that is the size of the image.
