Prerequisite for Step2: ReadString (from Irvine32 Library) The ReadString procedure reads a string from the keyboard, stopping when the user presses the Enter key. Pass the offset of a buffer in EDX and set ECX to the maximum number of characters the user can enter, plus 1 (to save space for the terminating null byte). The procedure returns the count of the number of characters typed by the user in EAX. Sample call: .data ; input buffer ; holds counter buffer BYTE 21 DUP(0) bytecount DWORD ? remrk, byte "Enter a string: ",0 .code main proc mov edxQFEESET buffer mov ecxSIZFQE buffer call Beadstring mov bytecQuntacax ; point to the buffer ; specify max characters ; input the string ; number of characters ReadString automatically inserts a null terminator in memory at the end of the string. The following is a hexadecimal and ASCII dump of the first 8 bytes of buffer after the user has entered the string "ABCDEFG": 41 42 43 44 45 46 47 00 ABCDEFG The variable bvteCount equals 7. Step2. Extend Stepl to get a string from a user using ReadString procedure. Please comment out the declarations of variables used in Step1 rather than deleting them. Your output should be shown as below. C C:\Windows\system32\cmd.exe Please insert a string: Towson_university Towson_university ytisrevinu_noswot Press any key to continue
