How to Join tables in the folder?

[GoDlike]

Hi,guys,here is my problem,

I have several tables in the folder,I want to join them together,merge same name columns,and match them by some conditions,here is my script,running this every time can only open the 1st table in the folder,this is my JSL script:

mypath = (mypath);

Set Current Directory( mypath );

y = Files In Directory( mypath );

For( i = N Items( y ), i > 0, i--,

  If( Ends With( y, "jmp" ),

  ,

  Remove From( y, i )

  )

);

n = N Items( y );

For( i = 1, i <= n, i++,

/* If the file is the first in the list, open it. Otherwise, open the table, join with the main table, and close the table just opened. */

    If( i == 1,

        mainDt = Open( mypath || y );

        dt = Open( mypath || y ) ;

        mainDt = mainDt << join ( dt,Merge Same Name Columns,

                                By matching Columns(:col1 = :col2),

                                Append to First Table );

        Close( dt, NoSave );

        Wait( 0 );

    )

  );  

/* Give the final table a name. */

mainDt<< Set Name( "Join Files" );

How can I realise this function?

thanks for help.
