ahhhh... my bad... sorry 'bout that... i've been thinking about this, too... 
'else' and 'otherwise' mean the same thing... what they seem to be looking for 
is 'aswell'...


foo := 0;
while foo < 100 do
   begin
     inc(foo);
   end;
aswell
   begin
     dec(foo);
   end;


either 'aswell' or 'aswellas'... while foo is less than 100 increment foo as 
well as decrement foo when it is no longer less than 100...

i don't see a need for it because in this case if one wants foo to only get to 
99, then they should use 99 as their count...


foo := 0;
while foo < 99 do
   begin
     inc(foo);
   end;


at the end of the loop, foo will equal 99... but it is also a very simple example...

it seems that way... but it doesn't mean that we have to use it... we can stay 
with the traditional ways and means within whatever it becomes as long as they 
don't change with these undesirable extensions...
