Intrinsic-47 RlIn

47: real:= RlIn(device);

This intrinsic gets a real number from the specified input device. It converts the number from ASCII digits into binary form. After a number is read in, RlIn is ready to read the next number. Non-numeric characters, such as spaces and commas, are skipped. This intrinsic does not return until a number is read. The number must be terminated by a non-numeric character.
