When you say F and G can only be defined at runtime, are you wanting to
dynamically generate Ada code at runtime and then execute it, or are you
just wanting to execute the same Ada code, but with different search
parameters and different sized arrays ?

I think the next stage is to try and find out what is so special about
F and G; you clearly need discriminated records, but I'm not yet 100%
convinced, for example, you need generics if this is just searching
for optimised values.

Also, can you talk about how these arrays are populated in the first
place and how that population process fits into the overall program
structure ?

Simon.
