user input and program design

Hey everyone,
I was writing some pseudocode to a very basic program and I was just wondering about something in my design, this is all in pseudocode (obviously :p ):

Code:

---

int main()
{
        Prompt for amt_requested
        Get amt_requested
        IF (amt_requested != 0)  AND  ( amt_requested <= 1000)
                Prompt for interest_rate, loan_duration
                Get interest_rate, loan_duration
        ENDIF

      WHILE (amt_requested != 0 )  AND (amt_requested <= 1000)
                  loop body
      ENDWHILE
}

---

What I was trying to accomplish is I want to run the loop until a sentinel (is that the right word?) value is entered (in this case 0 or anything over 1000), and I wanted to make sure that if a user enters a 0, they dont have to trudge through entering 2 more values for the other variables if they will never be used, so I wrote an if statement that does an initial check on the first value entered,now I was wondering if this is sloppy, or cumbersome, or redundant, anything like that. Thanks yet again for the help! -Chap

There's a bit redundancy, and maybe some logic problems, like what happens if they enter a negative number?

Code:

---

int main()
{
        Prompt for amt_requested
        Get amt_requested

        WHILE (amt_requested > 0 )  AND (amt_requested <= 1000)
        {
                Prompt for interest_rate, loan_duration
                Get interest_rate, loan_duration
                ... process amt or store it for later processing
                Prompt for amt_requested
                Get amt_requested //new amount or sentinel to end
        }  // ENDWHILE
}

wow darryl, thanks a lot, I'm an idiot! I didnt even think of receiving the other data in the loop body! That changes the whole game, haha. Thanks a lot for the help!
