1. Write a Procedure that inputs a string of Alphabets into a buffer. The caller passes Offset Address of a Storage Area and Maximum length of string. When this procedure is called it displays message "Please Enter a string of Alphabets ". If user presses Enter Key it returns to the caller. If during input, user presses a key other than Alphabet or Enter key, the procedure rejects that key code and prints the above message again. Use Irvine library procedure ReadChar to build this procedure.
