 Insert Hader comments:

Add below method on the EditorScripts class: 

public void comments_insertHeader(Editor e)

{

    e.unmark();

    e.gotoLine(1);

    e.gotoCol(1);

    e.insertLines('// Changed on ' + date2str(today(),123,2,1,3,1,4, DateFlags::FormatAll ) + ' at ' + time2str(timenow(), 1, 1) + ' by ' + curuserid()+ '\n');

}

For Testing Go to the new jobs right click Scripts -> comments-> InsertHeader -> click on that you will get comment on your code header side.

Start comments:

Add below method on this class EditorScripts , and test in the job

public void comments_Started(Editor _editor)

{

    int startLine = _editor.selectionStartLine();

    int endLine   = _editor.selectionEndLine();

    int i;

   // #define.comment('//')

    _editor.unmark();

    for (i = startLine; i <= endLine; i++)

    {

        _editor.gotoLine(i);

        _editor.gotoCol(1);

        //_editor.insertString(#comment);

        _editor.insertLines('// Changes started on ' + date2str(today(),123,2,1,3,1,4, DateFlags::FormatAll ) + ' at ' + time2str(timenow(), 1, 1) + ' by ' + curuserid() +'\n');

    }

}

End comments:-

Add below method on this class EditorScripts , and test in the job

public void comments_END(Editor _editor)

{

    int startLine = _editor.selectionStartLine();

    int endLine   = _editor.selectionEndLine();

    int i;

   // #define.comment('//')

    _editor.unmark();

    for (i = startLine; i <= endLine; i++)

    {

        _editor.gotoLine(i);

        _editor.gotoCol(1);

        //_editor.insertString(#comment);

        _editor.insertLines('// Changes End on ' + date2str(today(),123,2,1,3,1,4, DateFlags::FormatAll ) + ' at ' + time2str(timenow(), 1, 1) + ' by ' + curuserid() + '\n');
