Scale Basic 4.2E Tutorial

Event Driven Programming

This section provides an introduction to event driven, computer program design.

Program Design

The first step in computer programming is to create a ‘program design’. The first mistake that a

programmer can make is to give insufficient attention to designing a program. Give extra

attention to this phase of programming; you will be well rewarded for your effort. Programming

will be easier and it will be less likely that you will have to start over again because the program

doesn’t do what the customer wants.

There are many books written on program design. This manual uses the following program

design process:

1. describe the application. Many times this will be provided by your customer.

2. list the results (outputs) are to be accomplished.

3. list the inputs are needed to get the results.

4. describe the program functions that are needed.

The above process should be done with close consultation with the user of the program (your

customer). Usually, the customer describes the problem and the programmer takes notes and

asks questions. Then the programmer writes a draft of the program design asking the customer

questions as they occur. Then the customer is given a copy of the program design for approval.

At this time, the programmer should go over the design with the customer to make sure that

everything is covered.

Example: a customer presents the following application:

Application Description

The operator places containers on the scale and fills them with resin. An ‘Under-weight’ light

turns on while the container weight is below the target weight. There are 3 sizes of container,

each is filled with a different amount of resin. If the container is filled with too much resin, turn

on an ‘Overweight’ light until enough resin is removed for the container to be within

specifications.

Results / Outputs

Container filled with the proper amount of resin (3 sizes of container).

An ‘Under-weight’ light.

An ‘Over-weight’ light.

Inputs
