Lesson 7 - Subroutines

Flowcharts and sequencing

Software can be used to create sequences in a flowchart, to view onscreen simulations.

Examples include:
  • Flowol
  • Logicator
  • Crocodile Clips

Basic flowchart symbols

Name Symbol Usage
Terminator

Starts or stops a process.
Input or output

An input is data received by a computer. An output is a signal or data sent from a computer.
Process

An instruction or a command.
Decision

A decision, either yes or no. For example, a decision based on temperature that turns a central heating system on or off.
Line tool
