Hello all.

I hope someone can help me as how to do this has completely slipped my
mind, and I'm having trouble finding what I'm looking for in the Ada
LRM (83) and Barnes.

I have a function, let's call it Text_IO.Name which returns a string.
If I have an object let's say File_Name, what would be the correct (or
best) way to declare that object in order for the statement:

File_Name := Text_IO.Name (File);

(or something similar with slices?) to work without me getting a
constraint error by trying to assign a string of n characters to an
object /=n characters long.

Should I be using subtypes here or what.

I'm sure this will appear to be a really stupid question, but at the
moment I'm being frustrated and I can't think straight!

Thanks in advance.


Best Regards
