In that code it's clear that the "case" statement goes between ( ) so
its "end" is the one before ")".

So I see:

  a)   while ( EXPRESSION )  ; end

or:

  b)   while ( EXPRESSION ) ; do CODE ; end

both are valid. But in case EXPRESSION contains some "end" keyword and
option a) is used, then ensure that EXPRESSION goes between ( ).
