W3COUNT W3LIMIT | E3COUNT | E3COUNT

> Description

>   Returns the number of bytes already written there.

> Changes from previous versions

>   New with Natural Version 6.2: The size of the output area is no longer limited by internal settings during compile time. Therefore the maximum size is only limited by the maximum size of a Natural dynamic variable and the parameter settings used for the RPC or DCOM server. The return value of `W3MAXPAGE` can now be set within the program `W3LIMIT`, but has no effect on the maximum output size generated and stored internally.

> Parameters

>       1 W3MAXPAGE (I4) /* o/m : Maximum bytes possible
>       1 W3FREE    (I4) /* o/m : Free bytes
