Looping in Delphi

1. for-to-do
for i:=LowBound to HighBound do
begin
Code;
end;

2. for-downto-do
for i:=HighBound downto LowBound do
begin
Code;
end;

3. repeat-until
repeat
Code;
until Condition;

4. while
while Codition
begin
Code;
end;

Dispense with the begin & end to execute a single line
of code. repeat loops execute at least once. Use break,
continue or exit to modify/terminate loop execution.
