So your code doesn't solve the problem but it was nice enough for you to write some code to get him going.

I took your code and wrote it in python so he can see what it looks like:

Code: 
import csv

class CadConverter:
    
    def run(self, src_file, dst_file):
        codes = []
        new_lines = []
        with open(src_file, 'rb') as csvfile:
            lines = csv.reader(csvfile, delimiter='\n', quoting=csv.QUOTE_NONE)
            previousCode = None
            for row in lines:
                code = row[0].split()[-1].replace('"', '') # extract code
                if code == previousCode:
                    new_lines.append(row[0])
                else:
                    new_lines.append("END")
                    if code in codes:
                        new_lines.append("CONT " + code)
                    else:
                        new_lines.append("BEG " + code)
                        codes.append(code)
                    new_lines.append(row[0])
                    previousCode = code
            new_lines.append("END")
        with open(dst_file, 'w') as f:
            for line in new_lines:
                f.write(line + '\n')
    
def main():
    cadConverter = CadConverter()
    cadConverter.run('cadFile.txt', 'output.txt')

if __name__ == "__main__":
    main()

How so?

Only problem I see is it will add a BEG DCB line at the beginning, whereas his sample output does not. Easy edge case to fix.

This is what your program outputs:

this gets you close, just need to delete the first line of the output.



Code has gotten a little messy, could probably refactor that down and make it more readable.

Well you switched my AppendAllText to a A WriteLine, which of course adds an extra line break.

Console.Write would work better.
Click to expand...

Uhhh..... No, I used Console.Out.WriteLine. Did you look at the screen shot?

And its more then just a line break that is different with his output. Did you compare against his output?

Your keeping "B Go" etc...

I got that, the point being one adds a newline at the end, the other does not.

I didn't see that rule at first, my last example above handles it.

it should only add BEG ... above where the line had "B ..." instead of adding a BEG ... if it hasn't seen the code yet.

also the lines that have "B ..." should just be "..."

So "B GO" would be "GO" etc...

Also there is a trailing " on one of the lines at the end: BEG GO"

To get some practice my rusty C# skills, I wrote this up last night if you want another C# variation. Seemed to work fine in my testing. It's a console application. The exe accepts the old filename/path and new filename/path as the first two arguments (i.e. SurveyUtility.exe c:\temp\test.txt c:\temp\test2.txt). If the new file already exists, it'll end up overwriting it. I wasn't sure which you'd prefer, overwriting it, appending to it, or something else.

Code: 
using System;
using System.Collections.Generic;
using System.IO;
using System.Text;


namespace SurveyUtility
{
   class ConvertFile
   {
      static void Main(string[] args)
      {
         string oldFilePath = args[0];
         string newFilePath = args[1];

         string line;
         string currentCode;
         string previousCode = String.Empty;

         if (File.Exists(oldFilePath))
         {
            using (StreamReader srOldFile = new StreamReader(oldFilePath))
            {
               using (StreamWriter srNewFile = new StreamWriter(newFilePath, false))
               {
                  line = srOldFile.ReadLine();

                  while (line != null)
                  {
                     currentCode = line.Split(new string[] { "\"" }, StringSplitOptions.None)[1];

                     if (previousCode != currentCode && previousCode != "DCB" && previousCode != "CB" && currentCode != "DCB")
                     {
                        srNewFile.WriteLine("END");
                     }
                    
                     if (currentCode.Substring(0, 2) == "B ")
                     {
                        currentCode = currentCode.Substring(2);
                        srNewFile.WriteLine("BEG " + currentCode);
                        line = line.Replace("\"B ", "\"");
                     }
                     else if (previousCode != currentCode && currentCode != "CB" && currentCode != "DCB")
                     {
                        srNewFile.WriteLine("CONT " + currentCode);
                     }

                     srNewFile.WriteLine(line);

                     previousCode = currentCode;
                     line = srOldFile.ReadLine();

                     if (line == null)
                     {
                        srNewFile.WriteLine("END");
                     }
                  }
               }
            }
         }
      }
   }
}

C# without any hard-coded codes like DCB or CB.

To test on compileonline:
Code: 
using System;
using System.Collections.Generic;
using System.IO;

namespace ACAD
{
    class Program
    {
        static void Main(string[] args)
        {
            string sourceFile = "input.txt";
            var codes = new List<string>();
            var code = "";
            string previousCode = "";

            foreach (var s in File.ReadAllLines(sourceFile))
            {
                var finalLine = s.Replace("B ", "");
                code = finalLine.Split('"')[1];
                if (!code.Equals(previousCode ))
                {
                    if (codes.Contains(previousCode))
                    {
                        Console.WriteLine("END");
                    }
                    if (!finalLine.Equals(s))
                    {
                        if (!codes.Contains(code))
                        {
                            codes.Add(code);
                        }
                        Console.WriteLine("BEG " + code);
                    }
                    else if (codes.Contains(code))
                    {
                        Console.WriteLine("CONT " + code);
                    }
                    previousCode = code;
                }
                Console.WriteLine(finalLine);
            }
            if (codes.Contains(previousCode ))
            {
                Console.WriteLine("END");
            }
        }
    }
}

To produce an actual file:
Code: 
using System;
using System.Collections.Generic;
using System.IO;

namespace ACAD
{
    class Program
    {
        static void Main(string[] args)
        {
            string sourceFile = @"c:temp\input.txt";
            string destFile = @"c:temp\output.txt";
            var codes = new List<string>();
            var code = "";
            var output = new List<string>();
            string previousCode = "";

            foreach (var s in File.ReadAllLines(sourceFile))
            {
                var finalLine = s.Replace("B ", "");
                code = finalLine.Split('"')[1];
                if (!code.Equals(previousCode))
                {
                    if (codes.Contains(previousCode))
                    {
                        output.Add("END");
                    }
                    if (!finalLine.Equals(s))
                    {
                        if (!codes.Contains(code))
                        {
