1. Exercise 1
Part1: Compile the Assembly source program:
Assume Cs: Code
Code segment
MoV ah, 2
MoV DL, 3
Add DL, 30 h
Int 21 h
MoV ah, 2
MoV DL, 6
Add DL, 30 h
Int 21 h
MoV ah, 4ch
Int 21 h
Code ends
End
PS: I am familiar with MASM, so I used this compiler.
When the call was made, the ends was accidentally converted into an end, and an error was returned. The compilation was successful only after the change.
Part2: compile, connect, run, and debug the source program t1.asm.

I prefer reading e-books, which is convenient. There are a lot of professional PDF books in my computer. It would be great if I could read e-books. If I went to a bookstore to buy paper books, I always felt inconvenient, we have to carry a book that is so thick; and our professional books are all foreign books with big heads. One book requires 70 or 80 RMB, and I am always reluctant to buy it. I also seldom buy books. I don't know why. I am always excited to buy devices that read e-books. (That'

So far, you have only tried to use an SQL statement to retrieve data from a table. You can also use a SELECT statement to retrieve data from multiple tables at the same time. You only need to list the names of the tables from which data is to be retrieved in the from clause of the SELECT statement:
Select au_lname, title from authors, titles
When this select statement is executed, data is retrieved from both the table authors and table
