How to reverse a list of numbers within a line and on multiple lines?

    Hello, I wasn't sure where to put this but I was wondering if someone could help me with how to reverse a list of numbers horizontally and vertically.

    For example, I have this list: 4000, 6875, 6625, 2305
    But I want the numbers listed as: 23056625, 6875, 4000

    Or I have this list of numbers:

    4000,
    6875,
    6625,
    2305

    But I want the number listed as:

    2305,
    6625,
    6875,
    4000

    How could this be done with an UltraEdit script?

      Here is a commented UltraEdit script for both tasks as it reverses the order of the numbers within one or more selected lines and also the order of all selected lines. Everything in active file is selected if there is no selection on starting the script.

      Code: Select all

      if (UltraEdit.document.length > 0)  // Is any file opened?
      {
         // Define environment for this script.
         UltraEdit.insertMode();
         if (typeof(UltraEdit.columnModeOff) == "function") UltraEdit.columnModeOff();
         else if (typeof(UltraEdit.activeDocument.columnModeOff) == "function") UltraEdit.activeDocument.columnModeOff();
      
         // Select everything in active file if there is nothing selected on script start.
         if (!UltraEdit.activeDocument.isSel()) UltraEdit.activeDocument.selectAll();
      
         // Is the active file not an empty file?
         if (UltraEdit.activeDocument.isSel())
         {
            // Get type of line termination of active file as string.
            var sLineTerm;
            if (UltraEdit.activeDocument.lineTerminator < 1) sLineTerm = "\r\n";
            else if (UltraEdit.activeDocument.lineTerminator == 1) sLineTerm = "\n";
            else sLineTerm = "\r";
      
            // Get the selected block as an array of strings
            // with each string being a line of the selected block.
            var asInputLines = UltraEdit.activeDocument.selection.split(sLineTerm);
      
            // Remove the last string from the array if it is an empty string
            // because of selected block ends with a line termination and in this
            // case remember that the last selected line has also a line termination
            // as needed finally on writing back the output lines to the active file.
            var sLastLineTerm = "";
            if (!asInputLines[asInputLines.length-1].length)
            {
               sLastLineTerm = sLineTerm;
               asInputLines.pop();
            }
      
            // Create an array of strings each consisting of the non-digit
            // characters at end of each line. If all lines with all trailing
            // horizontal tabs and normal spaces removed end with a number, a
            // single comma or a single semicolon, the line ends of the input
            // lines are appended later to the reverse ordered lines.
            // Otherwise the line end of each line is kept as is.
