** SETX.DOC **

        SETX is a program to allow the input and display of some new
        fields added to the job control block (JCB) for AMOS/L 1.3
        operating system.  Specifically, the user name and default
        command line.  Additional options will be added as new fields
        are added.


        USAGE:  SETX {function{,string}}

                WHERE:
                        function is either:

                                USN for user name, and

                                CMD for command line.

                        string is the new information for the field.
                        Only the first 19 characters for user name and the
                        first 29 characters for command line are used. 
                        All excess characters are thrown out.  If string
                        is an asterisk (*) alone, the field selected is
                        cleared.

                NOTE:   If SETX is entered without any functions a usage
                        message is displayed.  If a function is used without
                        any string the current value is displayed.
