Make that: "Interrupt names must must contain only characters that take 1 space to print, and must be no longer than 10 characters, or unique and without garbage when blindly truncated to 10 characters, or in a special form that can easily be understood and compressed to <= 10 characters. The special forms are..." Similarly for device names (max length 4 or 5) and sleep message strings (max length 6). > We should just change systat, IMHO, but I know it's not easy. It's impossible to make changes that increase display resource requirements without breaking something. Either small displays stop working or scrolling is required. Bruce
