Is there a portable way to handle data elements of type: string?
(Any attributes which can be accessed for instance.)
As for constant strings:
line1: constant string := "Some text.";
begin
put_line (line1);
put_line (line1'last);
....
procedure string_op (ip_text: IN STRING) is
begin
?????
Thanks,
RC1

Type String is simply a one-dimensional array type, its declaration is
type String is array(Positive range <>) of Character;
from ARM 3.6.3(4), so all attributes of array types are defined for
String.

ip_text'First yields the index position of the first element of the actual
parameter.
ip_text'Last yields the last index position of the string.
ip_text'Range is shorthand for ip_text'First .. ip_text'Last.
ip_text'Length yields the length of the actual argument; it's the same
value as ip_text'last - ip_first + 1.
What are you trying to do, exactly?

..
Unless the string has length zero, in which case Ip_Text'Last <
Ip_Text'First.
