argCount

argCount() Function

• Introduced in version 1.3b51

Is used to determine the number of arguments that have been passed to a user defined function.

User functions are defined with the defineFunction(), once you have defined the function you can call it is you would call any of the existing functions. You can then use the argCount() function to determine how many arguments were passed when it was called.

Once the number of arguments have been determined you can use arg() to retrieve them.

Usage

Example

An example of a simple macro that would be defined as a user defined function. This function will add together

all of the arguments that are passed to it.

[h: total = 0]
[h,count(numArgs): total = total + arg(roll.count)]
[r: total]
