Ok I have this huge Q Basic program that I have to write and I am having a very difficult time writing it and i could really use some help.... Ive been staring at it for a while and its giving me a headache
Instructions:
The Federal Aviation Administration would like you to develop a program to report the number of passengers who fly out of a variety of airports.
Begin the project by asking the user whether the application is the one desired. This will give the user the option of exiting the program if it were run by mistake. Edit the answer for a case insensitive yes/no response, and only prepare the data file when the user responds ‘YES’.
Include in the project, a module which interactively builds an input file with the data listed below. Name the input file DATA1.DAT
Edit the airline field to insure that it contains only one of the following airline codes:
USA for USAir
AAL for American Airlines
DAL for Delta Airlines
Edit the Passenger load field to insure that no flight carries over 300 passengers.
The project should then contain a module to prepare a control break report passed upon the city to summarize and report passenger usage. Use the DATA1.DAT file as input for this module.
Input:
The input data below consists of airline flights containing the departure city, the airline used and the number of passengers on the specific flight. Enter the data below when building DATA1.DAT. The input records have already been sorted in ascending sequence by city to assist you in the development of your program.
List of City, Airline, and Passenger………
Output:
The output from the project is the airport usage report. The report is a control break report based upon the city. The report contains the city, the airline, and the number of passengers.
Intermediate totals should be printed for each city showing the total flights for each airline that services the city. The total number of passengers fro the city should also be printed.
At the end of the report, print the total passengers for all airports, the number of airports processed and the average number of passengers per airport. The report should be group indicated by city.
A sample of the report is shown below……..
Those are the instructions... heres what I got so far....

Its giving me a headache looking at this and I could really use some guidance on the module I'm on right now.... I have a good amount of the Flow Charts and hierarchy chart done already its just these last 2 modules that I'm lost in...
Never mind I've given up on this program its too stressful... mods can lock it
hey JKLE, if youre willing to give it a little while longer, someone around here may be able to help :) The clever coder types pop in a bit less frequently :)
In the interim, im sure you could find a more specific help forum for this stuff ?
good luck... Im a hardware guy so can be of no help at all Im afraid :(

Except headaches, what's your problem in particular with the above listing?
oh no i figured it out... i just needed some time away from it but i got it.... i wasn't referring to the fact that no one responded I was just stressed at it lol
no worries guys I figured it out thanks for the help tho!!!
I have no idea what it was all about but Im glad it was sorted !

Hope you didn't GOSUB everything because they give me headaches too. SUBs and FUNCTIONs are your friends.
I have to support a production application that uses QBASIC on DOS and your thread made me dust off my old books. I was working on it actually during my lunches, creating menus, error trapping, etc. Glad you got it working though. :)

no yea I know what your saying, my professor said he wanted 6 gosubs or moduals, there was a problem with a if statement and i forgot to close a mod as well :lol:
all stupid things that threw off the entire program
