Modify the dateDemo program.

Instead of 16 bit short packed date format, use 32 bit long packed date format.

Accept as input 4 digit year full year, month number, and day

Prompt user by "Enter your birthdate (full year, month, day): "

Read input as integers. Do computations and conversions and then output the result as a 32-bit hexadecimal number

Example:

Input: March 26, 1948. (input: 1948, 3, 26). Output will be 079C031A.

Input: October 12, 1957 (input: 1957, 10, 12). Output will be 07A50A0C

program dateDemo;

#include( "stdlib.hhf" )

static

day: uns8; month: uns8; year: uns8; packedDate: word;

begin dateDemo;

stdout.put("Enter the current month, day, and year: "); stdin.get(month, day, year);

// pack the data into the following bits: // // 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 // m m m m d d d d d y y y y y y y

mov(0, ax);

mov(ax, packedDate); //just in case there is error.

if(month > 12) then stdout.put("Month value is too large", nl);

elseif(month = 0) then stdout.put( "Month value must be in the range 1..12", nl );

elseif( day > 31 ) then stdout.put( "Day value is too large", nl );

elseif(year > 99) then stdout.put( "Year value must be in the range 0..99", nl );

else mov( month, al ); shl( 5, ax ); or( day, al ); shl( 7, ax ); or( year, al ); mov( ax, packedDate );

endif;

// Okay, display the packed value: stdout.put( "Packed data = $", packedDate, nl );

// Unpack the date: mov( packedDate, ax ); and( $7f, al ); // Retrieve the year value. mov( al, year );

mov( packedDate, ax ); // Retrieve the day value. shr( 7, ax ); and( %1_1111, al ); mov( al, day );

mov( packedDate, ax ); // Retrieve the month value. rol( 4, ax ); and( %1111, al ); mov( al, month );

stdout.put( "The date is ", month, "/", day, "/", year, nl );

end dateDemo;

Read month into a byte Read day into a byte Read 4-digit year into a word. Project 2: Combine month, day and year in a double word as long packed date. Then break long packed date into month, day and year parts. 1. 2. Example: July 22, 1985 0 0 0 0 0 1 1 1 month %0000_0111 day 960001-0110 year-60000 0111-1100 0001 month day 000 1 0 1 1 0 year= | 0| 0| 0| 0| 0| 1| 1| 1| 1| 1| 0| 0| 0| 0| 0| 1 Pack the month, day, and year into a double-word as shown below. packedDate= | 0| 0| 0| 0| 0| 1| 1| 1| 1| 1| 0| 0| 0| 0| 0| 1 0 0 0 0 0 11 1 0 0 0 1 0 1 1 0 Prompt to read all three elements as follow: "Enter year (YYYY), month, and day : Also, make sure that your program do not reject 4-digit number for year
