switch ( Expression ) ScopeStatement

I see that the syntax for 'switch' is ... switch ( Expression ) ScopeStatement and ScopeStatement is either a BlockStatement or a NonEmptyStatement. Meaning that switch (i) j = k; is valid syntax! Why is that? -- Derek Parnell Melbourne, Australia skype: derek.j.parnell

Re: casting int[] to bool[]

d to use 'ints' as bool values you have to provide your own conversion routine.

and you can NOT going to be using the data in other CPU architectures, then the simplest is to just copy out the RAM bytes to disk.
