Allows programs to open data files in specified directories as if they were in the current directory.  APPEND [[drive:]path[;...]] [/X[:ON | :OFF]] [/PATH:ON | /PATH:OFF] [/E] APPEND ;    [drive:]path Specifies a drive and directory to append.   /X:ON        Applies appended directories to file searches and                application execution.   /X:OFF       Applies appended directories only to requests to open files.                /X:OFF is the default setting.   /PATH:ON     Applies the appended directories to file requests that already                specify a path.  /PATH:ON is the default setting.   /PATH:OFF    Turns off the effect of /PATH:ON.   /E           Stores a copy of the appended directory list in an environment                variable named APPEND.  /E may be used only the first time                you use APPEND after starting up your system.  Type APPEND ; to clear the appended directory list. Type APPEND without parameters to display the appended directory list.
