# Transform integer into a coded string

Posted on 2004-08-08

I would like to do the following:

I have a integer which I would like to transform into a certain string (so it is not recognizable as a number).

Example:
Integer = 250

The digits must be translated into capital alpha's.
0 := K, 1 := B, 2 := M, 3 := P, 4 := F, 5 := W, 6 := R, 7 := S, 8 := O, 9 := Z

I would like to do this in a function with a less as code as possible.
Who can supply me with such a function.

This is what I have now:

function GetalCoderen(Const N : Integer) : String;
var GecodeerdGetal : String;
L, P : Integer;
begin
GecodeerdGetal := IntToStr(N);
L     := Length(GecodeerdGetal); //Hulpvariabele voor lengte
P     := 1;             //Positie binnen de tekst
While P <= L do
begin
// Translate digits into code > 0 := K, 1 := B, 2 := M, 3 := P, 4 := F, 5 := W, 6 := R, 7 := S, 8 := O, 9 := Z
If (GecodeerdGetal[P] = '0') then
begin
Delete(GecodeerdGetal,P,1);
Insert('K',GecodeerdGetal,P);
end;
If (GecodeerdGetal[P] = '1') then
begin
Delete(GecodeerdGetal,P,1);
Insert('B',GecodeerdGetal,P);
end;
If (GecodeerdGetal[P] = '2') then
begin
Delete(GecodeerdGetal,P,1);
Insert('M',GecodeerdGetal,P);
end;
If (GecodeerdGetal[P] = '3') then
begin
Delete(GecodeerdGetal,P,1);
Insert('P',GecodeerdGetal,P);
end;
If (GecodeerdGetal[P] = '4') then
begin
Delete(GecodeerdGetal,P,1);
Insert('F',GecodeerdGetal,P);
end;
If (GecodeerdGetal[P] = '5') then
begin
Delete(GecodeerdGetal,P,1);
Insert('W',GecodeerdGetal,P);
end;
If (GecodeerdGetal[P] = '6') then
begin
Delete(GecodeerdGetal,P,1);
Insert('R',GecodeerdGetal,P);
end;
If (GecodeerdGetal[P] = '7') then
begin
Delete(GecodeerdGetal,P,1);
Insert('S',GecodeerdGetal,P);
end;
If (GecodeerdGetal[P] = '8') then
begin
Delete(GecodeerdGetal,P,1);
Insert('O',GecodeerdGetal,P);
end;
If (GecodeerdGetal[P] = '9') then
begin
Delete(GecodeerdGetal,P,1);
Insert('Z',GecodeerdGetal,P);
end;
Inc(P);
end;
Result := GecodeerdGetal;
end;

or simplier (thanks to esoftbg :-)

function GetalCoderen(Const N : Integer) : String;
var
Letters :  string;
i: integer;
begin
Letters := 'KBMPFWRSOZ';
try
result := IntToStr(N);
for i := 0 to 9 do begin
result := StringReplace(result, IntToStr(i), String(Letters[i+1]), [rfReplaceAll]);
end;
except
result := ''; // or raise an exception
end;
end;
