Description of window flags (specifically "$")

[Christian Taylor]

Hello screen-users,

I'm using "caption always" with the string escapes %(+ or -)Lw and %f to 
display the window flags. However, on some systems every window has a "$" 
flag, while on other systems (running the same screen version of 4.00.02), no 
window has this flag. I have no idea what this means, since I can't find a 
description of the window flags anywhere in the screen manual. Googling 
doesn't help either.
Does anyone know where to find this information?

Thanks,

Christian Taylor
