Try this:

```program decimalToBinary;

const v:array[0..7] of byte=(1,2,4,8,16,32,64,128); {powers of 2}
bin:array[false..true] of char='01';
oct:array[0..7] of char='01234567';

{Decimal to binary}
function dec2bin(b:byte):string;
var s:string;
i:byte;
begin
s:='';
for i:=7 downto 0 do
s:=s+bin[(v[i] and b=v[i])];
dec2bin:=s;
end;
```
