To remove a line by line number, you can use something like this (no it isn't Sacky's function, i have just writted it now! and work):

pawn Code:

fdeleteline(filename[], line)
{
  new count, string[256], File:file, File:temp;

  file= fopen(filename, io_read);
  temp = fopen("tmpfile.tmp", io_write);

  while (fread(file, string))
    if (++count != line)
      fwrite(temp, string);

  fclose(file);
  fclose(temp);

  file= fopen(filename, io_write);
  temp = fopen("tmpfile.tmp", io_read);

  while (fread(temp, string))
    fwrite(file, string);
    
  fclose(file);
  fclose(temp);
  fremove("tmpfile.tmp");
}

If your file is file.txt, and it contain this:

Code:

sd
afd
hgfgh
gfjg

if you do

pawn Code:

fdeleteline("file.txt", 3);

then file.txt will now contain

Code:

sd
afd
gfjg
