Compare command

    Purpose:  Compares the contents of two blocks of memory.

    Format:   C range address

    Remarks:  The contents of the two blocks of memory are compared; the
              length of the comparison is determined from the range. If
              unequal bytes are found, their addresses and contents are
              displayed, in the form:

              addr1  byte1  byte2  addr2

              where, the first half (addr1  byte1) refers to the location
              and contents of the mismatching locations in range, and the
              second half (byte2  addr2) refers to the byte found in ad-
              dress.

              If you enter only an offset for the beginning address of
              range, the C command assumes the segment contained in the
              DS register. To specify an ending address for range, enter
              it with only an offset value.

    Example:  C 100 L20 200

              The 32 bytes (20h) of memory beginning at DS:100h are com-
              pared with the 32 bytes beginning at DS:200h. L20 is the
              range.
