[Query] For loop to import txt file and close txt file one by one

Hi, can someone teach me how to run For loop to,

import txt file -->

run a formula -->

save the file in the same folder -->

close the file -->

find next txt file

 

I have many files, so can't open all of them to process the formula.

Thanks in advance.

This example May help to find the solution:

// Initialization
Names Default To Here( 1 );
clear log();

// prepare source and destination directory
show(get path variable("SAMPLE_IMPORT_DATA"));
show(get path variable("TEMP"));

basepath_str = "$SAMPLE_IMPORT_DATA";
resultpath_str = "$TEMP" || "\jmp\";

// create folder for destination if not existing
If( Directory Exists( resultpath_str ),
 ,
 Create Directory( resultpath_str )
);

// read filelist
f_lst = Files In Directory( basepath_str );

// go through all csv files, open, add formula and save
dt_lst = {};
For( i = 1, i <= N Items( f_lst ), i++,
 If( Ends With( f_lst[i], "csv" ),
  cdt = Open( basepath_str ||"\"|| f_lst[i] );
  Insert Into( dt_lst, cdt );
  Show( cdt );
  cdt << New Column( "Formulat_row", Formula( Row() ) );
  cdt_fullfilename = resultpath_str || (cdt << get name) || ".jmp";
//  Close( cdt, save( resultpath_str || (cdt << get name) || ".jmp") );
 )
);
