Is there anyone who can translate this from geekSpeak to normalHumanSpeak?
(sorry; I'm no programmer)
Since I am a geek this is hard for me to do and I might fail, but my comments might help a little.
It is possible to build a custom function as well as a custom command. Unlike a custom command a custom function can be used in an expression. This is because it generates or returns a value.
Consider this in a button script:
on mouseUp put next(5) end mouseUp
function next x -- returns the number after x return x+1 end next
This will put 6 into the message box.
Just as the definition of the custom command "mouseUp" starts with 'on', the definition of the custom function "next" starts with 'function'.
Just as the custom command "mouseUp" has a name, the function has a name. The function name is "next".
It takes one parameter; it is named x.
It returns a value. The return command takes an expression. In this case it is x+1.
When next() is called it is passed the value 5, which becomes the value for x. This is added to 1 and returned. Thus the command in the mouseUp handler gets the value 6.
This can be applied to the quoting function.
In the example, q() is called with the value "I do." which becomes the value of the parameter named 'what'.
The value of 'what': I do.
The constant 'quote' is equivalent to a string containing a single double quote character.
The value of the expression in the return command is this: "I do."
Thus the answer command is equivalent to this: answer "She said, " & quote & "I do." & quote
The line in the answer dialog box is this: She said, "I do."
Since I am a geek, I am probably leaving out some crucial component for understanding this. I may have paid the cost to learn that component long ago and have forgotten what it takes to understand that.
