Quoting Mitchell N Charity off-list: >C99 requires a single _declarator_ to support 12. But note C99's >"Implementations should avoid imposing fixed translation limits >whenever possible.".
I know about the array-of-arrays factor all too well. (I tend to use the [x,x] notation when not paying attention). But as a declaration has to specify how many levels of indirection (pointer-to-pointer-to-pointer-to.....) we are dealing with, a limit seemed possible nonetheless. In fact Mitchell was kind enough to provide me with a full quote of the standard, which recites that: >The implementation shall be able to translate and > execute at least one program that contains at least one > instance of every one of the following limits: and our declarator limit above is one of them. Of course, this is an "AT LEAST" limit, so..... </OT> -Federico ----- Original Message ----- From: "Bill N1VUX" <[EMAIL PROTECTED]> To: "Steven W.
