I have a function that tests for a series of different conditions

The above does not work as the 'case...of' is not considered to be a loop.
Error: BREAK not allowed.
I could just exit the function, using 'exit' instead of 'break' but I
think I need to free the mylist TStrings.
Is there a way of doing this or is my best way just to replace 'break'
with 'mylist.free' and 'exit'?
If you use a try/finally block (and you always should when allocating resources)
then an exit will go through the finally block. So you can simply use exit.
mylist:=TStringlist.Create;
try
Case i of
// Use exit
end;
finally
MyList.Free;
end;
