I've written several functions, which I reuse. Is it possible to make it so that the parameters I pass are optional? If they are not passed, it could revert to a default value. For example, in one of my functions, I have two optional parameters. So currently, if I want to call it, I have to write the following

Code:
extractFunction("","")  ; - - -  To use default values

or
Code:
extractFunction("2","1")  ; - - -  To use custom values


Is it possible to do something where the person calling the values doesn't need to know that there are 2 parameters? IE, just this

Code:
extractFunction()

You forgot to read the "functions" help page in the manual? Right?

Code:
extract(15)

extractFunction(arg1=10, arg2="hello") {
 ;function body
 msgbox, %arg1%`n%aurg2%
}


Read the help file page, for a certain limitation of default values

I normally read the documentation, but didn't think to do so here. I could do without the attitude, but I appreciate the help. Thanks, it's exactly what I needed.
