Example:
I have the following thing:
c1: = 'data';
c2: = 'data';
c3: = 'data';
c4: = 'data';
c5: = 'data';

that routine I can use to concatenate these fields within a for or while. s1: = s1 + c?

As in most other programming languages you cannot iterate over separate variables.

do something like

var
  C: array [1..5] of string;
  I: Integer;
  S: string;
begin
  C[1] := 'data1';
  C[2] := 'data2';
  C[3] := 'data3';
  C[4] := 'data4';
  C[5] := 'data5';
  S := '';
  for I := Low(C) to High(C) do
    S := S + C[I];
end;

You have to use a pointer "^" in order to achieve this.

s1: = like knowing the content of c1 if this within s2??????

yodaMage, even using pointers may not york.
Nothing hinders the compiler to use a register for some of the variables.

Nope = no

Simplemente no puedes hacerlo porque el Delphi es un lenguaje estructurado que no esta pensado para eso. Lo que te plantean son alternativas: utilizar punteros, poner las variables en arrays.

Tanslation:

Nope=no (that was obvious ;-))

Simply you cannot make it because Delphi is a structurec languaje non thought for that. What they are giving to you are work arrounds: pointers, put the variables in arrays ...

Think that in Basic you can do many things that you can't in structured languajes. That's because you can mess up Basic code so easily if you're not very organized.
