There are times when existing programs are insufficient to accomplish a needed task. We can modify existing applications or write programs from scratch.
JAWS scripting is an example of modifying the JAWS screen reader program.
A script is a mini computer program that contains sequences of individual steps used to activate and control a wide variety of computer processes. The action a script performs ranges from simply entering repetitive strings of data, to many of the standard routines your computer does constantly as part of its operation.
Scripts or combinations of scripts and functions control most JAWS’ behavior. Scripts analyze what actions are taking place in an application and determine how to handle the screen reading for you.
Script files also contain functions. Like a script, a function is also a sequence of statements that perform a given task. However, functions differ from scripts in that you cannot activate them with a keystroke.
Programs are modified in many different ways.
