Perfectly reasonable. I will attempt a few examples.
String Function ReformatPhoneNumber (string sNumber)
;Outputs my preferred phone number format: 800-555-8355 (Tell Me service)
Let sNumber = StringReplaceSubstrings (sNumber, "(", Null ())
Let sNumber = StringReplaceSubstrings (sNumber, ")", Null ())
Let sNumber = StringReplaceChars (sNumber, " ", "-")
Return sNumber
EndFunction
Then in another function or script you can use this functions as many times
as you like with a statement such as:
Let sPhone = lvGetItemText (hWnd, iCurrentChild, 2)
Let gsVCAContactNumber = ReformatPhoneNumber (sPhone)
This will grab the string in the 2nd Colum of the selected item in a list
view and convert it to the desired format. I store this in a global
variable so it can be used later by another script.
Besides being more understandable and reusable, functions are also more
maintainable. If I decided I now prefer all my phone numbers read to me as
"800.555.8355", all the necessary changes can be made in one place. Nothing
else should be effected.
Many functions will have a return type of Int and have both a Return True
and Return False statements inside the function based on some conditional
logic. Make sure that all conditions return a value and that the function
does not exit without assigning a return value. Note that the value after
the Return keyword does not always have to be a variable. You can also
directly return a value or the return value of another function, such as:
Return True
Return 5
Return StringReplaceChars (sNumber, " ", "-")
Another hard concept for some to wrap their heads around is am statement
like:
Let i = i + 1
This is impossible in Algebra and the natural world, but is common in the
"virtual land" of computer programming! In programming languages, the equal
sign is a symbol to store a value into a variable. Variables in computer
terms amount to be a memory location or processor register. Therefore the
the above statement does not say that the value of i is equal to the value
of i plus 1. It actually says to take the value stored in the variable
stored in memory, which is located with the pointer referred to as i, and
add the integer 1 to this value. This is communally called incrementing.
Then the result is stored back in the same memory location, again referred
to as i.
