1 XDIR
    XDIR is a command procedure that uses the DIRECTORY command to 
output a file of file names for use in SVN, BUILD, BURST, TPOUT, etc.

    This procedure takes up to 4 parameters. The first parameter is
passed on to the directory command.  If the second parm contains a 
".", it is taken as the output file name.  The rest of the parameters 
are treated as keywords.  If a keyword equals "NAME", only the name 
of the file is output (no $ 'P1' 'P2' 'P3'), additionally if no target 
file is specified, "X.NAX" is used.  If a keyword equals "NOV", the 
version number and semicolon are removed from the output.  Control Y 
terminates and closes the output file.
