Ärende: Final code
==================
 SD> I couldn't resist relaxing a bit and working on some code, so I got
 SD> the code finalized and it compiles.  Now to see if it actually
 SD> works. :)  

here's another post that only pulls out the space delimited fields and this one
is zero-based... field 0 is 'A', 1 is 'Daryl', 3 is the comma delimited section
and so on...

another item of interest about this routine... it looks like, by default, it
extracts words that are space, tab or semi-colon (;) delimited... but anyway,
there it is :)

program extract_word_test;

const
  t1_str : string = 'A Daryl Stout SY,SH,KL,DR,DN,UP,';
  t2_str : string = 'PR,MS,MMV,CC,RC,PW,CU,QK,MB,MU,CB,';
  t3_str : string = 'TB=05/05/02/01/03/01/01/60/60:120/120 ';
  t4_str : string = 'LOCAL ANSI 5-4-10 4880 307 18:53';

var
  my_cnt : integer;
  my_str,
  result_str : string;

function extractword(str : string; n : integer) : string;
var
 count : integer;
 i : integer;
 len : integer;
 done : boolean;
 retstr : string;

begin
  retstr := '';
  len := length(str);
  count := -1;
  i := 1;
  done := false;
  while (i <= len) and (not done) do
    begin
      while ((i <= len) and
             ((str[i] = #32) or
              (str[i] = #9) or
              (str[i] = ';'))) do
        inc(i);
      if i <= len then
        inc(count);
      if count = n then
        begin
          retstr[0] := #0;
          if (i > 1) then
            if str[i-1] = ';' then
              retstr := ';';
          while ((i <= len) and
                 ((str[i] <> #32) and
                  (str[i] <> #9) and
                  (str[i] <> ';'))) do
            begin
              inc(retstr[0]);
              retstr[ord(retstr[0])] := str[i];
              inc(i);
            end;
          done := true;
        end
      else
        while ((i <= len) and
               ((str[i] <> #32) and
                (str[i] <> #9) and
                (str[i] <> ';'))) do
          inc(i);
    end;
  extractword := retstr;
end;

begin
  my_str := t1_str + t2_str + t3_str + t4_str;
  writeln(my_str);
  for my_cnt := 0 to 9 do
    begin
      result_str := extractword(my_str,my_cnt);
      writeln(my_cnt, ' : ''',result_str,'''');
    end;
end.
