Manipulating strings

Manipulating strings

[Hung Huynh]

Hi!

Let's say I've got this string: "this is my string     "

As you can see there's uneccessary spaces at the end of the string. I
want to send just the string without the spaces into a procedure. How do I
do this?
My string is output from another procedure.
I don't want to do it with the help of a function that is recursivly
defined, neither should it be with any kind of loop.

Thanks!

   If you're using Ada 95, just try to call :

   Trim (Source => Your_String, Side => Right)

   See  RM95-A.4.3(89-96)  for details,  and  BTW  carefully read  the
chapter A.4,  you'll get  everything  you want about   string handling
(except general regexeps, anyone working on a rx binding ?). Note that
the RM95 is available in hypertext from the URL :

   http://lglwww.epfl.ch/Ada/

   among plenty of interesting things.

   If you're not using Ada 95, just download the GNAT sources (or look
at the adainclude in the binary distributions), and grab the code from
a-strfix.adb (URL plus good advices in my signature ;-).

: Thanks!
