    I have an assignment to do, inwhich i have to initiate a time delay of n-seconds. I don not know how to start.
    Do I initiate the internal clock to start counting? If so, how? I heard something about typing n clock.com, in the assembly line but i am not sure.

    And how do I know which inputs the clock signal is coming into?

    Rearranging Bytes
    16 bytes are residing in locations starting from 2400H. Transfer those bytes in locations starting from 2500H in such a way that 1st 8 bytes in the 1st block should appear at last 8 locations of the 2nd block and the last 8 bytes in the 1st block at 1st 8 locations of the 2nd block.

    Checking bits of a word.
    A word is residing in location 2400H. Write a program to check each bit of the word starting from MSB and fill 16 locations starting from 2500H, with either OOH or FFH depending on the bit, FFH if the bit is ‘1’ and 00H if the bit is ‘0’ . Also count the no. of 1s and 0s (in BCD) in the word and store them respectively at 2600H and 2601H.

    Filling up 128 locations.
    Write a program to fill up 128 locations starting from 2400H with bytes in the following pattern: 1st 64 location to be filled up as 00H, 11H, 22H, …. FFH, 00H, 11H, 22H… and so on and the last 64 locations to be filled up as FFH, EEH, DDH, … OOH, FFH, EEH and so on.

    Write program in Assembly language which accepts two decimal digits from
    its user, prints a new line on the display
    screen, and if the first digit is larger than the second, displays the
    average of the two digits (to the
    nearest whole number) and otherwise displays the square root of the
    product of the two digits (to
    the nearest whole number). Then the program should return to DOS control.
    Thus, if the user types
    93
    then the program displays
    6
    and if the user types
    39
    then the program displays
    5
    Hint: Think of easier way for square root calculation

    When we declare a variable like

    var dw 92F3h its OK, but if we write it like
    var dw B2F3, it gives an overflow error. Now to overcome this, we need to give a 0 before it.

    var dw 0B2F3h. Now this works.

    My question is why in certain cases we have to give the 0 ?

    to estimate the size of the block and store the count in BCD in COUNT.

    39.[FONT=&quot] [/FONT]A block starts at 0C20H and ends where 4 consecutive 00H are followed by FFH. Write a program to estimate the size of the block and store the count in BCD in COUNT.

    58. Two blocks of bytes exist in 0C20H and 0C40H. When the interrupt 6. 5 key is pressed, for each pressing the larger of 1st bytes of each block is to be written in location 0C60H. Each block consists of 10 bytes and hence after 10 interrupts a new block shall exist in OC60H with larger bytes of the two blocks. Disable the interrupt after the new block formation.
