The limit on the length of the PATH is in the fact that Command.com will not pass a line longer than 127 characters. Since 5 characters are used by the word "path=", the command.com will truncate the actual path to 122 characters. The reason the %path% ideas don't work is because the varible expansion occurs in command.com before the line is send out and is therefore truncated. There is no reasonble limit to length of the path if you can get it into the environment. There are programs which will do this such as ADDPATH and LONGEST. They are in the IBMSYS library of Compuserve. I don't know where to get them on this network. The best solution is the Command.com replacement 4DOS. It has a command line of 255 characters and a command ESET which allows you to directly edit the path. 4DOS is so great that this is the least of the benefits you can get from using it. -- cj
