In MS-DOS versions 3.1x-4.x, if a "PATH \;.." statement is used and an executable (or .BAT) file is found in the directory that translates to the "\" portion of the PATH statement, the system stops (hangs).


Microsoft has confirmed this to be a problem in MS-DOS versions 3.1, 3.11, 3.2, 3.21, 3.22, 3.3, 4.0, 4.0a, and 4.01. This problem does not occur in later versions of MS-DOS.


Reversing the order of the path items (to read ..;\) eliminates the problem.


This type of path is common when software is organized onto logical drives and all necessary files are loaded in the root or in a directory below the working directory.
