A.4 String Handling

1/2
This clause presents the specifications of the package Strings and several child packages, which provide facilities for dealing with string data. Fixed−length, bounded−length, and unbounded−length strings are supported, for String, Wide_String, and Wide_Wide_String. The string−handling subprograms include searches for pattern strings and for characters in program−specified sets, translation (via a character−to−character mapping), and transformation (replacing, inserting, overwriting, and deleting of substrings).
