Exit using Return Key

[mcslemon@hotmail.com (mcslemon)]

Help!

Doing an assignment and have nearly finished, but have come to a
problem!

I'm using get(conv) to read input from the keyboard....this is fine,
but CONV is assigned to a type, so can't vary from the type.

The person can either enter a phrase to continue, or hit enter to exit
the program.

Is there a way of reading the line length or something so if they type
the phrase it continues or exits on return key hit.

Starts using:

  type Measurement is (Ins,Mil,Cm,Km,Lbs,Kg);
  package measurement_inout is new enumeration_io(measurement);
  subtype Distance is Measurement range Ins..Km;
  subtype Weight is Measurement range Lbs..Kg;
  use measurement_inout;
  Conv : Measurement;
..

..

..

loop
     New_Line;

       Put("Please Enter Unit to Convert From");
        New_Line;

        Get(Conv);

reads the CONV there...

Any ideas!
