#X text 40 23 This is useful for managing a variable number of arguments. When it receives the 'args' message \, [pdcontrol] outputs the loaded arguments.

#X text 48 295 Above there's a simple abstraction to show how it works. Note how dollar signs (such as "\$0" \, "\$1" or "\$2-x") get expanded unless you escape them with a backlash ("\$2-x" may appear as an unexpanded symbol \, but it actually gets expanded if this abstraction is called inside another that contains arguments).;
