Vora,
Since you saw fit to attempt to answer the questions, I must take issue
with some of your answers.
Question 1 is fine.
Question 2, however, is not. As submitted, the code will not work due to a
missing quote at the end of the Country string assignment. Therefore, the
FIND function will never be seen.
Question 3 had the correct answer, but for the wrong reason. True, a
trailing @ sign is needed on the input statement. But even with that the
code will not find 'Sue' because the input had 'sue' (lower case). The
input statement also looks strange. I believe a space is required between
the character designator and the column range (e.g., $ 1-4 instead of $1-4).
Still, Howard's response is the best one. Don't ask this group to do your
homework for you. But with any submission, make sure it's typed correctly
if you hope to get reliable assistance.
