//正确
if A = B then
begin
DoSomething;
DoSomethingElse;
end
else
begin

以下的少数变化可以被采用：
//正确
if Condition then
begin
DoThis;
end else
begin
DoThat;
end;
//正确
if Condition then
begin
DoThis;
end
else
DoSomething;
//正确
if Condition then
begin

//下面的方式可能不被关心，但却是值得赞扬的：
if Condition then
DoThis
else DoThat;
