Examples:

This script defines a macro called TypeArgs. If three arguments are passed to the TypeArgs macro, the macro types the three arguments to the Script window.

Def TypeArgs 
{
      if (macro.narg != 3)
      {
            type "Error! You must pass 3 arguments!";
      }
      else
      {
            type "The first argument passed was %1.";
            type "The second argument passed was %2.";
            type "The third argument passed was %3.";
      }
};

If you define the TypeArgs macro as in the example, and then type the following in the Script window:

TypeArgs One;

Origin returns the following to the Script window:

Error! You must pass 3 arguments!

If you define the TypeArgs macro as in the example, and then type the following in the Script window:

TypeArgs One Two Three;

Origin returns the following to the Script window:

The first argument passed was One.

The second argument passed was Two.

The third argument passed was Three.
