Hi,

for a long time I've been interested in Ada but hadn't played with it.

Now I bit the bullet and I am trying to create a small (Windows) program 
that:
1) reads a string from STDIN (yet to do)
2) fetches the contents of the PATH environment variable (done)
3) splits that content in individual paths (???)
4) tries to match the inputted string with part of each path (to do)
5) outputs only the matched paths (to do)

I found out the hard way that Ada is very strict about bounded versus 
unbounded strings.
So I had to convert the output of 2) to an unbounded string, because I could 
not know it's length in advance.

Now I am a bit stuck splitting the string of paths;
I use GNAT.String_Split.Create, but it needs a (bounded) String as input.
However, I only have an unbounded string.

QUESTION: How can I convert an unbounded string to a standard (bounded) 
string?
                    A standard string must be defined with a fixed length in 
advance, which I do not know at the time ...

TIA,
   Arie
