Re: 'first of strings returned from a function should be 1?

["David C. Hoos, Sr." <david.c.hoos.sr@ada95.com>]

What's wrong with Result_String (Result_String'first) for getting at the
first character of a function result?

From my own experience, I know that it is easy to write a poor function
returning a string result of which the first subscript is not 1, and I
always make the effort to slice (if necessary) the result into the range 1
. result'length, but if you're using
something you can't change, then something like 
New_Result (1 .. Result_String'length) :=
Result_String(Result_String'first .. result_String'first +
Result_String'length -1)
will do the job.
