Unfortunately, we currently do not have an up-to-date FAQ.

There is all sorts of stuff like that in the Ada.Strings.* packages.
See section A.4 of the online LRM at
http://adaic.org/standards/95lrm/html/RM-TOC.html . More generally,
read *everything* in Annexes A and K before asking any more "does Ada
have XYZ?" questions.

Strings in Ada are particularly tricky for newcommers. One trap is
underuse of perfectly sized string constants. Most strings get their
value once and never need it changed. If that is the case, its fairly
easy to declare the string at the point its value is known, with the
perfect bounds, by using a string constant (possibly inside a
"declare" block). If you do that, it becomes very easy to deal with.

Also, note that a lot of string handling stuff that requires routines
in other languages is trivial in Ada. For instance, you can take a
slice of any array (including strings) with something like
"Array_Name(5..8)". Any two arrays of the same type (including
strings) can be concatenated with "&". Most numeric types (and
enumerations) can be converted to strings with the 'image attribute.
