Problems in GNAT with get_line

Problems in GNAT with get_line

[Peteri Matti]

	Hi

  I've got this little problem that for some reason get_line doesn't stop 
to wait the user input.

  So, I use GNAT95, and in my main program I call this subprogram where I 
make these declarations
 
	ansStr	:string(1..stringMax);
	strLgt	:integer;

and in the body I put something on the screen with put_line and put. 
After this I want to read a string with a command

	get_line(ansStr,strLgt);

but to my suprise my program doesn't wait for the input and as I have on 
the next line

	put(ansStr & "foo");

there's nothing intelligent on ansStr. And I get a "raised constraint 
error"...

  And if I use simply get(ansSTr); it stops waitin' for user input and waits 
and waits and nothing goes on...

  So where could I go wrong? At the GNAT examples there is an example 
that uses the same kind on declarations and commands.

  Thanks in advance - I'm sure it's some stupid little mistake but I 
haven't been able to detect it myself.

Try put a SKIP_LINE in front of your GET_LINE.
