HELP!!!!

I a trying to convert the following "static" ada data
structure to a structure that can be created dynamically,
ie via the "new" ada function, and setting the two
constrants at that time.

I can not seem to find anything that will work (as
far as type declarations) short of
moving the second level array (Host_array) into
the top level structure (system_config_type) and
making it 2d.  That is TOO ugly!!!!

Can one of you ada guru's help me out?
the current type definitions (ie the "static"
version) are below....

thanks!!!!
