Hello,

 From C++ point of view, it is criminal way to use ARRAY when you 
have much safer TEMPLATES.

Please specify what errors you are getting? The info you provided 
is bit less.

>question: using large arrays in that way is a problem >with other 
>platforms, like HP-UX or Solaris ?

provided..if possible plz attach CODE SNIPPET.

Madhav.
