Hello Dmitry,
Why no use pointer to string !!
type T_Ptr_String is access String;
And now your strings can have the length you want ... but you should
define function to construct your strings tha way (make something like
a class in a package and use it)
It should be as or more flexible than the unbounded strings...
Is it usefull?
Xavier
