Characters package

Characters package

[Anderson]

I want to use the to_lower and to_higher function in the characters package
in ada. I can do it by using

with Ada.Characters.Handling;
use Ada.Characters.Handling;

but I am told I is bad code to make it visible throughtout the program, so
how do I declear it as a package
ie package char ..... ?

I haven't seen your program, so I don't know if the above is bad style
or not.  Some alternatives are:

    Move the use clause into a smaller scope.

    Eliminate the use clause, and call it using the full name
    Ada.Characters.Handling.To_Upper.

    Say "with Ada.Characters.Handling; use Ada;", and call it using the
    name Characters.Handling.To_Upper.

    Rename Ada.Characters.Handling to, say, Chars, and write
    Chars.To_Upper.
