Mostafa:
Let me also see if I can add to what Don so ably said.
compile: this is a term used by just about every programming language.
Computers don't understand the words, if, then else, saystring, etc.
What they do understand is 1's & 0's. Well that's pretty rough stuff.
So there's a sort of middle step called machine language. It, too, is
not easy for programmers to write. When u compile a script, it takes
the statements u make like
typeString("Mostafa")
& converts it to machine language that the computer can understand.
A function can be either built into the programming language or
created by the user. In the case of jaws, if it isn't activated by a
keystroke, it's a function. This is totally simplified, but here's
code for a function that I created, therefore, it's called a
"user-defined function":
void function MyName ()
say("my name is Mostafa", ot_message)
endFunction
script test ()
MyName()
endScript
The script test does nothing but calls the function myName by using
the function's name, followed by a left & right parentheses pair. The
code immediatly jumps to the function myName(). Your name will be
spoken, & the script will quit.
The word void preceding the name of the function means it does not
return anything. We'll get to that in a minute.
Another word for parameter is also argument. Let's take this rather
simplistic script/function pair & expand it a bit further.
void function MyName (string name) ;this is called a function declaration
say("name, ot_message)
endFunction
script test ()
MyName("my name is Mostafa") ;what's in the parentheses is a parameter
endScript
Note the changes. The first change is that the parentheses that
surround the function myName are no longer empty, but contain the
words (string name). This tells the compiler to expect that a value is
going to be given to that function, that it is a string, & that it's
called name. the 2nd change occurs in the script, where, again, the
parentheses surrounding the function's name are no longer empty but
contain the quoted string ("my name is Mostafa"). That value is known
as a parameter or argument.
Now, let's take this still rather simplistic code & decorate it a
little further.
string function MyName () ;this is called a function declaration
return "my name is mostafa"
endFunction
script test ()
var
string name
let name = MyName()
say(name, ot_message)
endScript
This time, the word string before the name of the function myName
tells u that the function is going to give back or return a string.
The script test declares a variable (which is just a name of something
that can change) of type string that I called name when it says var
string name. The statement let name = myName() says that I want to
take what the MyName() function returned & store it in the variable
called name. It then calls the function myName() & the function tells
the script that the value to be returned is "my name is mostafa". That
value is then spoken & the script ends.
This is not an easy concept. You'll need to understand it though in
order to script or do most any programming languages effectively. If
you've ever done algebra, then the concept of variables is similar,
e.g., x & y can mean anything depending on the equasion.
Parameters are separated by commas, so, the Jaws say function contains
2 parameters, that is, what u want spoken & something called the
output mode. Thus, in the statement say("my name is Mostafa",
ot_message) say is the name of the function, its 2 parameters are the
quoted string "my name is Mostafa" & the output mode of ot_message.
Well that's all for now, folks. I think it's probably more than
enough, actually.
Good luck beginning scripters!
